General Description

The LTC®3527/LTC3527-1 are dual high efficiency, step-up DC/DC converters in a space saving 16-lead 3mm × 3mm QFN package.

Battery life is maximized with a 700mV startup voltage and operation down to 500mV once started.

The SHDN and PGOOD pins enable the converters to be sequenced or started together.

Overview

LTC3527/LTC3527-1 Dual 800mA/400mA, 1.2MHz/2.2MHz Synchronous Step-Up DC/DC.
