OB3622M - High Precision Non-isolated Power Switch

Download the OB3622M datasheet PDF. This datasheet also covers the OB3622M-On variant, as both devices belong to the same high precision non-isolated power switch family and are provided as variant models within a single manufacturer datasheet.

General Description

OB3622M is a high current precision, non-isolated power switch for LED lighting.

It works under transition mode.

It significantly simplifies the LED lighting system design by eliminating the auxiliary winding inductance and works under low current.

Key Features

  • including LED string open protection, LED string short circuit protection, cycle-by-cycle current limiting, built-in leading edge blanking, VDD under voltage lockout (UVLO), over temperature protection (OTP), etc. OB3622M is offered in SOP8 package.

On-Bright confidential to OB3622M High Precision Non-isolated Power Switch GENERAL DESCRIPTION OB3622M is a high current precision, non-isolated power switch for LED lighting. It works under transition mode. It significantly simplifies the LED lighting system design by eliminating the auxiliary winding inductance and works under low current. A 650V power switch is also integrated into the device. The LED current can be adjusted externally by the sense resistor Rs at CS pin and high precision constant current regulation is realized.
