The EV4700-S-00A is the Evaluation Board designed to demonstrate the capabilities of MP4700 for TV backlighting applications. The MP4700 is a high efficiency step-down converter controller designed for driving the high brightness LEDs.
With a 250-300V input VIN and an 8-18V power supply for MP4700, the EV4700-S-00A can drive a LED string up to 200V, and the LED current is regulated to 250mA. The EVB realizes input UVLO by INUV pin, the PWM dimming can be implemented by applying a PWM dimming signal on PWM pin. The short LED load protection and Over-Voltage protection are included.
