OB3399TAP-H - High Precision Offline LED Power Switch

Download the OB3399TAP-H datasheet PDF. This datasheet also covers the OB3399PAP-On variant, as both devices belong to the same high precision offline led power switch family and are provided as variant models within a single manufacturer datasheet.

General Description

OB3399x is a primary side regulation off-line LED lighting power switch which can achieve accurate LED current.

It significantly simplifies LED lighting system design by eliminating the secondary side feedback circuitry.

Key Features

  • including Cycle-by-Cycle current limiting, VDD clamp and UVLO. Excellent EMI performance is achieved with On-Bright proprietary frequency shuffling technique. OB3399x is offered in DIP8 package.

OB3399x High Precision Offline LED Power Switch GENERAL DESCRIPTION OB3399x is a primary side regulation off-line LED lighting power switch which can achieve accurate LED current. It significantly simplifies LED lighting system design by eliminating the secondary side feedback circuitry. Proprietary Constant Voltage (CV) and Constant Current (CC) control is integrated as shown in the figure below. The LED current (CC control) can be adjusted externally by the resistor Rs at CS pin. OB3399x offers comprehensive protection coverage with auto-recovery features including Cycle-by-Cycle current limiting, VDD clamp and UVLO. Excellent EMI performance is achieved with On-Bright proprietary frequency shuffling technique. OB3399x is offered in DIP8 package.
