MP3383 - Step-Up WLED Controller

Description

The MP3383 is a step-up controller with four LED current channels, designed to drive WLED arrays for large LCD panel backlighting applications.

The MP3383 can expand the number of LED channels with two or more ICs in parallel sharing a single power source.

Features

  • include over-current protection (OCP), over-temperature protection (OTP), undervoltage protection (UVP), over-voltage protection (OVP), LED short and open protection, and inductor and diode short protection. The MP3383 is available in SOIC-16 and TSSOP-16EP packages.

MP3383 4-String, Max 400mA/String, Max 80V VOUT, Step-Up WLED Controller DESCRIPTION The MP3383 is a step-up controller with four LED current channels, designed to drive WLED arrays for large LCD panel backlighting applications. The MP3383 can expand the number of LED channels with two or more ICs in parallel sharing a single power source. The MP3383 employs peak current control mode with a fixed switching frequency (fSW) that is configurable via an external setting resistor. The MP3383 drives an external MOSFET to boost up the output voltage (VOUT) from a 6V to 33V input voltage (VIN) supply. It also regulates the current in each LED string to the value set by an external current-setting resistor. The MP3383 applies four internal current sources for current balancing.
