DESCRIPTION
1A, 2MHz Synchronous
Step-Up DC/DC Converter
in 2mm
× 3mm DFN
TheLTC3528-2isasynchronous,fixedfrequencystep-up
DC/DC converter with output disconnect. High efficiency
synchronous rectification, in addition to a 700mV start-
up voltage and operation down to 500mV once started,
provideslongerrun-timeforsingleormultiplecellbattery-
powered products.
A switching frequency of 2MHz 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 LTC3528-2 enters Burst Mode operation at light loads.
Anti-ringing circuitry reduces EMI by damping the induc-
tor in discontinuous mode. Additional features include a
low shutdown current, open-drain power good output,
short-circuit protection and thermal overload protection.
The LTC3528-2 is offered in an 8-lead 2mm
× 3mm ×
0.75mm DFN package.
