EV3363-J-00A

EV3363-J-00A is an evaluation board designed to demonstrate the capabilities of the MP3363, a fixed-frequency converter that is ideal for low-to-high current boost applications. Current mode regulation and external compensation components allow the MP3363 control loop to be optimized across a wide variety of input voltages. The MP3363 supports analogue dimming and pulse-width modulation (PWM) dimming on same pin. An input PWM signal with dimming frequency below 2KHz initiates PWM dimming, while an input PWM signal with dimming frequency above 5KHz initiates analogue dimming. Soft start, cycle-by-cycle current limiting, and input undervoltage lockout (UVLO) protection prevent the sensitive external circuitry from being damaged or overstressed during start-up or potential overload current conditions. The MP3363 is available in a TSOT23-8 package. Applications include 2 AA power backlighting, LCD backlighting and general lighting.
