OB3396 - High Precision Off-line Primary-Side PWM Power Switch

Download the OB3396 datasheet PDF. This datasheet also covers the OB3396-On variant, as both devices belong to the same high precision off-line primary-side pwm power switch family and are provided as variant models within a single manufacturer datasheet.

General Description

OB3396 is a primary side regulation off-line LED lighting controller 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 OVP, VDD clamp and UVLO. Excellent EMI performance is achieved with On-Bright proprietary frequency shuffling technique. OB3396 is offered in DIP8 package.

High Precision Off-line Primary-Side PWM Power Switch OB3396 GENERAL DESCRIPTION OB3396 is a primary side regulation off-line LED lighting controller 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 SOURCE pin. Device operates in PFM in CC mode as well at large load condition and it operates in PWM with frequency reduction at light/medium load. OB3396 offers comprehensive protection coverage with auto-recovery features including Cycle-by-Cycle current limiting, VDD OVP, VDD clamp and UVLO.
