Description

The EV4008-S-00A is designed to demonstratethe capabilities of MP4008. The MP4008 is acurrent mode controller designed for driving thehigh brightness Light Emitting Diodes (LEDs)with wide input voltage 9V-28V. It can be usedboth in Boost and SEPIC topologies.With a 20-48V power supply PVIN and a 9-28VIC supply for MP4008, The evaluation boardcan drive a single LED string with the LEDcurrent regulated to 350mA and VLED voltageup to 70V. Apply a PWM dimming signal to doPWM dimming. The Over-Voltage protection,short LED protection, short inductor/diodeprotection and over current protection areintegrated.
