Monolithic Power Systems MP2905

3V-28V Input, Hysteretic Synchronous Step-Down Controller

Overview

TopologyBuck Converter
Input voltage12 V
Switching frequency200-500 kHz
Output 11.8 V / 25 A
IC revision1.0

Description

The MP2905 is a hysteretic voltage-mode control,synchronous PWM buck controller. The output voltage can be regulated from 0.6V to 0.9*VIN. Itachieves high output current over a wide input supply range from 3V-28V.

MP2905 integrates an internal LDO regulator that makes the controller function at a wide input supply.

Hysteretic voltage-mode control provides fast transient response without additional loop compensation.

An adjustable soft-start prevents inrush current at turn-on. The device senses high-side switch voltage drop for hiccup current limit and shortcurrent protection. The frequency is adjustable from 200kHz to 500kHz.

The MP2905 is available in 10-pin MSOP package, provides a very compact system solution with minimal reliance on external components.
