DESCRIPTION
LT8210
High Voltage, High Efficiency Synchronous Buck-Boost
Converter with Input to Output Pass-Thru
Demonstration circuit 2814A-A is a high voltage, high
efficiency synchronous buck-boost DC/DC converter with
an input voltage range of 8V to 80V. After the part has
started, the input voltage can run down to 3.5V. It can
supply a 3A maximum load current with an output range
of 8V to 16V. The demo board features the LT8210EUJ
controller. The constant frequency current mode architec-
ture allows a phase-lockable frequency of up to 400kHz,
while an optional input or output current feedback loop
provides support for applications such as battery charg-
ing. With a wide input range, wide output range, and
seamless transfers between operation modes, the LT8210
is ideal for industrial, automotive, medical, military, and
avionics applications.
The converter has four modes of operation:burst, pulse
skip, forced continuous mode, or pass-thru. Pass-thru is
a feature that passes the input directly to the output when
All registered trademarks and trademarks are the property of their respective owners.
PERFORMANCE SUMMARY
the input voltage is within a user programmable window.
Switching losses drop to zero and efficiency is maximized.
For input voltage above or below the pass-thru window,
the buck or boost regulation loops maintain the output
at the set maximum or minimum values, respectively.
Reverse input protection is also implemented on this
demo board.
The available versions of the DC2814A are:

QUICK START PROCEDURE
Demonstration circuit 2814A-A is easy to set up to
evaluate the performance of the LT8210. Refer to the
followingprocedure:
1. With power off, connect the input power supply to VIN
(8V to 40V) and GND (input return).
2. Connect the 8V to 16V output load between VOUT and
GND.
3. Connect the DVMs to the input and the output.
4. Turn on the input power supply and then check for the
proper output voltages. VOUT should be between 8V to
16V, depending on the input voltage (see Figure4).
5. Once the proper output voltages are established, adjust
the loads within the operating range and observe
the output voltage regulation, ripple voltage and
otherparameters.
6. After the part starts, the input voltage can be reduced
to as low as 3.5V.
7. The input voltage may be raised up to 80V for short
periods of time.
Note:When measuring the output or input voltage rip-
ple, do not use the long ground lead on the oscilloscope
probe. See Figure1 for the proper scope probe technique.
Short, stiff leads need to be soldered to the (+) and (–)
terminals of an output capacitor. The probe’s ground ring
needs to touch the (–) lead and the probe tip needs to
touch the (+) lead.
