DEMO MANUAL DC1516A
LTC3833EFE
Wide Input Range,
High Efficiency Step-Down
DC/DC Converter
Other features of the board include a MODE jumper to
program either DCM or CCM with light or no load, a PLLIN
input for synchronizing the converter to an external clock,
a TRACK/SS pin, a PGOOD pin and an EXTV
CC
pin.
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 1.25"
×
0.5" area
on the board. The package style for the LTC3833EFE is a
20-lead TSSOP with an exposed ground pad.

DESCRIPTION
Demonstration circuit 1516A is a 1.5V/15A synchronous
buck converter operating with a switching frequency of
300kHz over an input voltage range of 4.5V to 24V. The
demo board comes in two versions. The -A version uses
inductor DCR current sensing with an iron powder inductor
for highest efficiency. The -B version uses a 2.5mΩ/1%
sense resistor for accurate current sensing with a low
DCR ferrite inductor. The fixed on-time valley current
mode control of the LTC
®
3833 allows for a fast load step
response (see Figures 4 and 5). The load step response
can be tested with the on-board load step circuit and a
bench pulse generator.
