Description

The LTC®3528/LTC3528B are synchronous, fi xed frequency step-up DC/DC converters with output disconnect. High effi ciency synchronous rectifi cation, 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 profi le 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, shortcircuit protection and thermal overload protection.

The LTC3528/LTC3528B are offered in an 8-lead 3mm × 2mm × 0.75mm DFN package.
