FEATURES
DESCRIPTION
The LTC
®
3528/LTC3528B are synchronous, fixed frequency
step-up DC/DC converters with output disconnect. High
efficiency synchronous rectification, in addition to a 700mV
start-up voltage and operation down to 500mV once
started, provides longer run time for single or multiple
cell battery-powered products.
A switching frequency of 1MHz minimizes solution
footprint by allowing the use of tiny, low profile induc-
tors and ceramic capacitors. The current mode PWM is
internally compensated, simplifying the design process.
The LTC3528 enters Burst Mode operation at light loads,
while the LTC3528B features continuous switching at light
loads. Anti-ringing circuitry reduces EMI by damping the
inductor in discontinuous mode. Additional features include
a low shutdown current, open-drain power good output,
short-circuit protection and thermal overload protection.
The LTC3528/LTC3528B are offered in an 8-lead 3mm
