DESCRIPTION

LTC7871/LTC7060

48V-to-14V, 6-Phase, 2.5kW Bidirectional Supply/

Charger

All registered trademarks and trademarks are the property of their respective owners.

Demonstration circuit 2886A is a high power, high effi-

ciency six-phase bidirectional converter featuring the

LTC

7871 and LTC7060. The terminals labeled VHIGH

and VLOW are either inputs or outputs depending on the

direction of power flow. When the switch at SW1 is in the

BUCK position, VLOW provides a 14V output and VHIGH is

the input with a range of 30V to 70V. When the switch

is in the BOOST position, VHIGH provides a 48V output

and VLOW is the input with a range of 10V to 14V. The

maximum VLOW current is 180A in both directions. The

maximum output power is 2.5kW when operating as a

buck within the input voltage range. When operating as

a boost, the maximum output power is 2.4kW when the

input voltage is 14V. External airflow is required when

operating at maximum power. The MOSFETs in each

phase are driven by the LTC7060 half bridge driver. Each

LTC7060 gate driver is placed next to the MOSFETs and

receives a PWM signal from the LTC7871.

The inductor current for each phase is sensed with a low

1mΩ sense resistor using a highly accurate AC/DC cur-

rent sensing architecture with low power dissipation. The

LTC7871’s constant-current loop provides a DC current

limit for the current flowing in or out of the V

LOW

terminal

depending on the state of the BUCK pin. This current can

be programmed with the SETCUR pin and monitored with

the IMON pin.

The DC2886A provides a SPI compatible serial port. With

a DC2026C (Linduino

One) demo board and QuikEval™

software on a host computer, the user can:

• Margin the regulated VLOW or VHIGH up or down.

•Margin the DC current limit up or down with the

SETCUR pin.

•Adjust the frequency spread and modulation rate of

the spread spectrum circuit, when spread spectrum

isenabled.

•Monitor the operational status and faults of

theLTC7871.

Additional features of the DC2886A include:

• Pin selectable light load operating modes

– Buck:FCM, pulse-skipping and Burst Mode

Operation

– Boost: FCM and pulse-skipping

• SYNC and CLKOUT pins

•Optional jumper to enable spread spectrum modulation

• RUN, FAULT, PGOOD and PWNEN pins

•BUCK pin to externally control the direction of

powerflow

• Footprint for an optional heatsink

Design files for this circuit board are available.

QUICK START PROCEDURE

Instructions for operating the DC2886A are below.

NOTE:Use short and thick cables with a sufficient current

rating. If batteries are used when testing the demo board,

always use suitable circuit breakers for safety.

Constant-Voltage (CV) Buck Mode

1. Refer to the connection diagram shown in Figure1.

2. Place SW1 in the BUCK position.

3. Connect the input supply to VHIGH and the load to

VLOW. Next connect the voltmeters to monitor VHIGH

and VLOW.

4. Turn on the V

HIGH

supply. With no load, slowly increase

the VHIGH supply until VHIGH reaches 30V. At this point,

14V should appear on VLOW. The regulation limits are

shown in the Performance Summary section.

5. Next, increase VHIGH to 48V. Recheck the regulation.

6. Apply load up to 180A across VLOW. Recheck

theregulation.

7. After the basic performance has been verified, the

other aspects of performance can be measured

andobserved.

5. Next, increase VLOW to 14V. Recheck the regulation.

6. Apply load up to 51A across VHIGH. Recheck

theregulation.

7. After the basic performance has been verified, the

other aspects of performance can be measured

andobserved.

Note:When measuring the output voltage or input

voltage ripple, be sure to measure directly across an

output or input capacitor. Do not use the ground lead

on the oscilloscope probe. See Figure3.

Constant-Voltage (CV) Boost Mode

1. Refer to the connection diagram in Figure2.

2. Place SW1 in the BOOST position.

3. Connect the input supply to VLOW and the load to

VHIGH. Next connect the voltmeters to monitor VLOW

and VHIGH.

4. Turn on the VLOW supply. With no load, slowly increase

the VLOW supply until VLOW reaches 10V. At this point,

48V should appear on the output. The regulation limits

are shown in the Performance Summary section.

Constant-Current (CC) Mode

The DC2886A can operate as a constant-current source

when operating either as a buck or a boost. There are the

setup instructions.

1. For buck operation, setup DC2886A as shown in

Figure 1. For boost operation, setup DC2886A as

shown in Figure2. The load will need to have a con-

stant-voltage mode.

2. If the converter is setup as a buck, the CV setting for

the load should be 10V or less. If the converter is setup

as a boost, the CV setting should be 40V or less.

3. Connect a bench voltage source to the SETCUR pin as

shown in Figure4. This could be either a DC voltage

or the output of a pulse generator.

4. Monitor SETCUR, IMON and ILOW or IHIGH while adjust-

ing the SETCUR voltage. Figure17 shows an example.

For buck to boost or boost to buck transition testing,

setup the DC2886A as shown in Figure5.

External Bulk Capacitance

Additional bulk capacitance may be required across the

input for either power flow direction, especially if operating

at or near full load with supply cables longer than 2 feet.

Depending on the supply cable inductance, when operat-

ing as a boost, an extra 10mF of bulk capacitance across

VLOW may be required. When operating as a buck, an extra

1mF of bulk capacitance across VHIGH may be required.

For buck/boost transition testing, this extra capacitance

should be added across both inputs. Likely choices for

the external capacitance are either aluminum electrolytic

or super capacitors with sufficient voltage rating.

Thermal Considerations

With full continuous load on the output in either direc

tion at room temperature ambient, 400LFM of airflow

is recommended with full load. All the efficiency curves

and thermal images shown in the Typical Performance

Characteristics section were taken with this amount of

airflow from an adjustable external fan. To further aid with

thermals, the DC2886A has three optional footprints for

a board mounted heatsink and DC fan. The heatsinks are

placed at HS1–HS3 on the bottom layer underneath the

power stages for phases 1and 2, phases 3 and 4 and

phases 5 and 6. The DC fan is mounted over the heat-

sink. Terminals labeled V

provide the fans with

power from VLOW. See Figure6 for details.

b. QuikEval can margin VLOW, VHIGH and the DC ILOW

current limit up or down by writing to the register

which controls the current source digital to ana-

log converter (IDAC) for the VFB

, VFB

HIGH

SETCUR pins. To use this feature, make sure the

Read Continuously button is not enabled. This but-

ton is gray when not enabled.

c. An optional design tool can be enabled from the

File menu. It calculates the required IDAC value to

margin the V

LOW

, V

HIGH

or DC I

current limit

to a given value. To use this tool, enter the values

for the feedback divider or SETCUR resistor and

then enter the value for the desired VLOW, VHIGH

or IL(MAX) which is the DC ILOW current limit. The

design tool will then provide the calculated IDAC

value. To update the LTC7871’s registers, enter the

calculated IDAC values in the dashboard and then

press the respective Update button.
