MP3362

Single-String, 3V Minimum V_IN, 36V V_OUT

Boost LED Driver

DESCRIPTION

FEATURES

The MP3362 is a fixed-frequency converter ideal

for low-current and high-current boost

applications. The low 0.2V feedback voltage

offers higher efficiency in white LED driver

applications.

•

3V to 36V Input Voltage Range

4A Peak Current Limit

0.3μA Shutdown Current

Low 200mV Feedback Voltage

Configurable 200kHz to 2.2MHz f_SW

Internal 80mΩ, 40V Power Switch

High Efficiency

Analog and PWM Dimming

Under-Voltage Lockout Protection

Open/Short LED Protection

Short FB Protection

The MP3362 regulates the output voltage up to

36V with efficiency as high as 95%. Current

mode regulation and external compensation

components allow the MP3362 control loop to be

optimized across a wide variety of input voltages.

The MP3362 supports analog dimming and

PWM dimming on the same pin. A <2kHz input

dimming frequency initiates PWM dimming,

while an >5kHz input initiates analog dimming.
