LTC3528 Datasheet 1mhz Synchronous Step-up DC/dc Converters

Manufacturer: Linear Technology Corporation

Overview: LTC3528/LTC3528B 1A, 1MHz Synchronous Step-Up DC/DC Converters in 3mm × 2mm.

General 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 footprint by allowing the use of tiny, low profile inductors and ceramic capacitors.

Key Features

  • Delivers 3.3V at 200mA from a Single Alkaline/ NiMH Cell or 3.3V at 400mA from Two Cells.
