MP3363

Single-String, 1.8V Minimum V_IN, 36V V_OUT Boost LED Driver

Datasheet

Description

The MP3363 is a fixed-frequency converter ideal for low-current and high-current boost applications. Its low 0.2V feedback voltage (V_FB) offers higher efficiency in white LED driver applications.

The MP3363 regulates the output voltage (V_OUT) up to 36V, with efficiency as high as 95%. 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 analog 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 analog dimming.

Soft start, cycle-by-cycle current limit, 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.

Advantages include:

Wide input voltage range and low shutdown current.
Internal power switch and high efficiency.
Analog dimming and PWM dimming.
Good circuit protection and small size available.
