DESCRIPTION

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.

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.

Soft start, cycle-by-cycle current limiting, and

input under-voltage lockout prevent

overstressing or damaging sensitive external

circuitry during start-up or potential overload

current conditions.

The MP3362 is available in a TSOT23-8

package.
