TYPICAL APPLICATION

DESCRIPTION

Dual Channel 550mA 1MHz

Synchronous Step-Up

DC/DC Converter

The LTC®3535 is a dual channel, synchronous, fixed fre-

quency step-up DC/DC converter with output disconnect.

Extended battery life in single AA/AAA powered products

is realized with a 680mV start-up voltage and operation

down to 500mV once started.

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 design

is internally compensated, reducing external parts count.

The LTC3535 features Burst Mode operation at light load

conditions allowing it to maintain high efficiency over a

wide range of load. Anti-ring circuitry reduces EMI by

damping the inductor in discontinuous mode. Additional

features include a low shutdown current of under 1µA and

thermal shutdown.

The LTC3535 is housed in a 3mm

× 3mm × 0.75mm

DFN package.
