DESCRIPTION
The MP3363 is a fixed-frequency converter
ideal for low-current and high-current boost
applications. The low 0.2V feedback voltage
(VFB) offers higher efficiency in white LED driver
applications.
The MP3363 regulates the output voltage
(VOUT) 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.
