DESCRIPTION
LTC3839EUH
Fast Transient
Step-Down DC/DC Converter
Demonstration circuit 1632A is a single output 1.5V/40A
dual phase synchronous buck converter operating with
a switching frequency of 300kHz over an input voltage
range of 4.5V to 14V. The controlled on-time valley current
mode architecture of the LTC3839 allows for a fast load
step response (see Figure 4). The load step response can
be tested with the on-board load step circuit and a bench
pulse generator.
Other features of the board include remote sensing, sel-
ectable light load operating modes of forced continuous
mode (FCM) and discontinuous mode (DCM), a PLLIN
pin for synchronizing to an external clock, a CLKOUT
pin, an EXTVCC pin to reduce losses in the controller, and L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear
Technology Corporation. All other trademarks are the property of their respective owners.
PERFORMANCE SUMMARY
RUN and TRACK/SS pins. Up to 12-phase operation can
be achieved by daisy-chaining the CLKOUT and PLLIN
signals of multiple boards and programming the relative
phase with the PHASMD jumper.
The demo board uses a high density, two sided drop-in
layout. The entire converter, excluding the bulk output and
input capacitors, fits within a compact 1.6˝ ×1.2˝ area
on the board. The package style for the LTC3839EUH is a
32-lead 5mm ×5mm QFN with an exposed ground pad.

QUICK START PROCEDURE
Figure 1. Proper Measurement Equipment Setup
Demonstration circuit 1632A is easy to set up to evalu-
ate the performance of the LTC3839EUH. Please refer to
Figure 1 for proper measurement equipment setup and
follow the procedure below.
1) With power off, connect the input supply, load and me-
ters as shown in Figure 1. Preset the load to 0A and VIN
supply to 0V. Place jumpers in the following positions:
JP1 RUN ON
JP3 MODE FCM
2) Adjust the input voltage to be between 4.5V and 14V.
VOUT should be 1.5V ±2%.
3) Next, apply 40A load and re-check VOUT.
4) Once the DC regulation is confirmed, observe the output
voltage ripple, load step response, efficiency and other
parameters.
Note 1. Use the BNC connector labeled VOUT to measure
the output voltage ripple.
Note 2. Do not apply the load from the VO_SNS+ pin to
the VO_SNS– pin. This may damage the converter. These
pins are only intended to monitor the voltage across the
bulk output capacitors at COUT1-4.
Load Step Testing (Optional)
Demonstration circuit 1632A provides a simple load step
circuit consisting of a MOSFET and sense resistor for each
rail. To apply a load step, follow the steps below.
1) Pre-set the amplitude of a pulse generator to 0.0V and
the duty cycle to 5% or less.
2) Connect the scope to the VOUT BNC connectors for
the rail under test with a coax cable. To monitor the
load step current, connect the scope probe across the
ISTEP± pins.
3) Connect the output of the pulse generator to the PULSE
GEN pin and connect the return to the GND pin.
4) With the converter running, slowly increase the ampli-
tude of the pulse generator output to provide the desired
load step pulse height. The scaling for the LOAD STEP
signal is 5mV/Amp.
