MP1608C - 5.5V 6A Synchronous Step-Down Converter

Description

The MP1608C is a monolithic, step-down switchmode converter with built-in internal power MOSFETs.

It achieves 6A of continuous output current (IOUT) from a 2.4V to 5.5V input voltage (VIN) range, with excellent load and line regulation.

The output voltage (VOUT) can be regulated to as low as 0.4V.

Features

  • Wide 2.4V to 5.5V Operating Input Voltage (VIN) Range.

MP1608C 5.5V, 6A, Synchronous Step-Down Converter with FCCM in SOT583 Package DESCRIPTION The MP1608C is a monolithic, step-down switchmode converter with built-in internal power MOSFETs. It achieves 6A of continuous output current (IOUT) from a 2.4V to 5.5V input voltage (VIN) range, with excellent load and line regulation. The output voltage (VOUT) can be regulated to as low as 0.4V. The constant-on-time (COT) control scheme provides fast transient response and facilitates loop stabilization. Fault protections include cycle-by-cycle current limiting and thermal shutdown. The MP1608C is well-suited for a wide range of applications including high-performance digital signal processors (DSPs), wireless power, portable and mobile devices, and other lowpower systems.
