MP3362 – SINGLE-STRING, 3V MINIMUM V_in, 36V BOOST LED DRIVER

PIN FUNCTIONS

Pin #

Name Description

Output switch node. SW is the drain of the internal N-channel MOSFET. Connect the

inductor and rectifier to SW to complete the boost converter.

VIN

Input supply pin. This pin can be connected to the regulator’s input supply or to the output

for bootstrap operation.

Error amplifier output compensation. Connect the COMP pin to a series RC network to

compensate the regulator control loop.

COMP

Enable and dimming pin. Used the EN/DIM pin to enable/disable the device, or to initiate

PWM dimming or analog dimming. The following conditions determine how this pin operates:

EN/

DIM

1. Keep the EN/DIM pin low for 20ms to disable the IC.

2. Apply a <2kHz PWM signal frequency to make the IC work in PWM dimming mode.

3. Apply a >5kHz PWM signal frequency to make the IC work in analog dimming mode.

Switching frequency setting and synchronization pin. Connect a resistor to this pin to

program the switching frequency. Apply a pulse signal between 200kHz and 2.2MHz to

synchronize the switching frequency.

OSC/

SYNC

Regulation feedback input. The regulation threshold is 0.2V.

Open LED protection pin. OVP pin senses the output voltage to protect the IC during open

LED operation.

OVP

GND Ground.
