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.
