L6382D

Power management unit for LED drivers

Datasheet - production data

Applications

 Dimmable / non-dimmable LED drivers

SO-20

Description

Features

 Integrated high voltage startup

 4 drivers for PFC, half-bridge and auxiliary

MOSFETs

 3.3 V microcontroller compatible

 Fully integrate power management for all

operating modes

 Internal two point VCC regulator

 Overcurrent protection with digital output signal

 Cross conduction protection (interlocking)

 Undervoltage lockout

 Integrated bootstrap diode

The L6382D device is suitable for LED drivers

embedding a PFC stage and a half-bridge stage.

The L6382D includes 4 MOSFET driving stages

(for the PFC, for the half-bridge, and for the

auxiliary MOSFET) plus a power management

unit (PMU) featuring also a reference able to

supply the microcontroller in any condition.

In addition to increasing application efficiency, the

L6382D device reduces the bill of materials as

different tasks (regarding drivers and power

management) are performed by a single IC, which

improves application reliability.
