Monolithic Power Systems MP2115

2A Synchronous Step-Down Converter with Programmable Input Current Limit

Overview

TopologyBuck Converter
Input voltage4.5-6 V
Switching frequency700-2000 kHz
Output 13.8 V / 2 A
IC revision1.0

Description

The MP2115 is a high frequency, current mode, PWM step-down converter with integrated input current limit switch. The step-down converterintegrates a main switch and a synchronous rectifier for high efficiency without an external Schottky diode. The input average current limit can be externally programmed. It is ideal for powering portable equipment that is powered by an USB port. The MP2115 can supply 2A of load current from a 2.8V to 6V input voltage. The output voltage can be regulated as low as0.6V.

The MP2115 is available in a space-saving 10-pin QFN package.
