MA5620 - 38V Synchronous Buck Controller

Datasheet Summary

Description

The MA5620 is a synchronous buck controller.

The device need externals high-side and external low-side power MOSFETs, and provides higher than 5A continuous load current and a wide input voltage from 8V to 40V.

Current mode control provides fast transient response and cycle-by-cycle current limit.

Features

- Wide 8V～40V Operating Input Range. - Externals high-side / low-side Power MOSFET Switches. - Output Adjustable : VFB (1.00V±2%). - Up to 97% Efficiency. - Internal Soft-Start and Fixed 160KHz Frequency. - Duty on ratio : 0% to 91% PWM control. - Cycle-by-Cycle Current Limit（or called Over Current Protection, OCP） - Thermal Shutdown Protection（or called Over Temperature Protection, OTP） - Input Under／Over Voltage Lockout. （UVLO／OVLO） - FB Over Voltage Protection. （OVP） .

MA5620 40V Synchronous Buck Controller with 2ch CC/CV  GENERAL DESCRIPTION The MA5620 is a synchronous buck controller. The device need externals high-side and external low-side power MOSFETs, and provides higher than 5A continuous load current and a wide input voltage from 8V to 40V. Current mode control provides fast transient response and cycle-by-cycle current limit. An internal soft-start prevents inrush current at turn-on, this device available in small TDFN-12L (3x3) package, provides a very compact solution with minimal external components.  FEATURES - Wide 8V～40V Operating Input Range. - Externals high-side / low-side Power MOSFET Switches. - Output Adjustable : VFB (1.00V±2%). - Up to 97% Efficiency. - Internal Soft-Start and Fixed 160KHz Frequency.
