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 foot-
print by allowing the use of tiny, low profile inductors 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 ×
2mm × 0.75mm DFN package.
