MP3437 - Synchronous Boost Converter

Description

The MP3437 is a 600kHz, fixed-frequency, highly integrated, synchronous boost converter with a wide input range.

The MP3437’s input voltage starts as low as 2.7V and supports up to 20W of load power from a 1-cell battery with integrated low RDS(ON) power MOSFETs.

Features

  • include programmable input under-voltage lockout (UVLO) protection and over-temperature protection (OTP). The MP3437 is available in a QFN-10 (2mmx2.5mm) package and a TSOT23-8 package.

MP3437 16VOUT, 9.5A, High-Efficiency, Fully Integrated, Synchronous Boost Converter DESCRIPTION The MP3437 is a 600kHz, fixed-frequency, highly integrated, synchronous boost converter with a wide input range. The MP3437’s input voltage starts as low as 2.7V and supports up to 20W of load power from a 1-cell battery with integrated low RDS(ON) power MOSFETs. The MP3437 utilizes a constant-off-time (COT) control topology, which provides fast transient response. The QFN package has a MODE pin that supports the selection of pulse-skip mode (PSM), forced continuous conduction mode (FCCM), and ultrasonic mode (USM) under lightload conditions.
