LTC3539 - 1MHz/2MHz Synchronous Step-Up DC/DC Converters

General Description

The LTC®3539/LTC3539-2 are synchronous, 2A step-up DC/DC converters with output disconnect.

Synchronous rectification enables high efficiency in the low profile 2mm × 3mm DFN package.

Battery life is extended with a 700mV start-up voltage and operation down to 500mV once started.
