OB3375 Datasheet High Performance Buck Led Driver

Manufacturer: On-Bright

Overview: OB3375 High performance buck LED driver GENERAL.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The OB3375 is a high efficiency LED driver designed for white LEDS and for large LCDS backlight.

OB3375 is built-in a quasi-resonant control method buck DC/DC converter.

The controller implements a peak current mode control scheme and an internal transconductance amplifier to accurately control the output current over a wide input and load conditions.

Key Features

  • to protect the system in various fault conditions such as Diode & Inductor short protection, CS open protection, MOS drain source short protection, LED+/LED- short protection, LED-/GND short circuit protection, LED open loop protection, Over temperature protection (OTP). The cycle-by-cycle current limit function limits the maximum current flowing through the external MOSFET. OB3375 is offered in SOP8 package.
