The EV3363-J-00A is an evaluation board designed to demonstrate the capabilities of Monolithic Power Systems’ MP3363, a fixed-frequency converter that is ideal for low- to high-current boost applications. The low 0,2 V feedback voltage offers high efficiency in white LED driver applications.
The MP3363 regulates the output voltage up to 36 V, with efficiency as high as 95%. Current-mode regulation and external compensation components allow the chip’s control loop to be optimised across a wide variety of input voltages. The converter supports analog dimming and pulse-width modulation (PWM) dimming on the same pin. An input PWM signal with dimming frequency below 2 kHz initiates PWM dimming, while an input PWM signal with dimming frequency above 5 kHz initiates analog dimming.
Soft start, cycle-by-cycle current limiting and input under-voltage 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.
