STOD1317B Datasheet high efficiency boost converter + LDO

Manufacturer: STMicroelectronics

General Description

The STOD1317B is a fixed frequency, high efficiency, boost DC-DC converter with cascaded LDO able to provide output voltages ranging from 6 V to 13 V starting with an input voltage from 2.6 V to 4.8 V.

The device is designed to supply loads that are very sensitive to output ripple such as AMOLED display panels.

A dedicated LDO is able to suppress any ripple and noise coming out from the DC-DC converter.
