LTC3528B-2 Datasheet 2mhz Synchronous Step-up DC/dc Converter

Manufacturer: Linear Technology (now Analog Devices)

General Description

The LTC®3528B-2 is a synchronous, fixed frequency step-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, provides longer run-time for single or multiple cell battery-powered products.

A switching frequency of 2MHz minimizes solution footprint by allowing the use of tiny, low profile inductors and ceramic capacitors.
