MA5603 Datasheet 38v Synchronous Buck

Manufacturer: Major Power Technology

Overview: MA5603 (Preliminary) 38V Synchronous Buck for LED Driver  GENERAL.

General Description

The MA5603 is a monolithic synchronous buck regulator, and step-down converter designed for driving up to 10 series white LEDs from a 38V system input.

The total LED driving current up to 2.5A , which is measured through an external current sense resistor.

Its low 200mV feedback voltage reduces power loss and improves efficiency.

Key Features

  • - Wide 8V to 38V Operating Input Range - Integrated two 140mΩ Power MOSFET Switches - Feedback Voltage : 200mV - Internal Soft-Start / VFB Over Voltage Protection - Stable with Low ESR Ceramic Output Capacitors - Fixed 240KHz Frequency - Current Limit , Thermal Shutdown and S.
