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.
