MA5603 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.
