OCP8178A - White LED Driver

Download the OCP8178A datasheet PDF. This datasheet also covers the OCP8178A-ORIENT variant, as both devices belong to the same white led driver family and are provided as variant models within a single manufacturer datasheet.

General Description

With a 40-V rated integrated switch FET, the OCP8178A is a boost converter that drives LEDs in series.

The boost converter runs at 600kHz fixed switching frequency to reduce output ripple, improve conversion efficiency, and allows for the use of small external components.

Key Features

  • integrated open LED protection that disables the OCP8178A to prevent the output voltage from exceeding the IC's abs.

WWW.ORIENT-CHIP.COM OCP8178A White LED Driver With Digital and PWM Brightness Control ◼ General Description With a 40-V rated integrated switch FET, the OCP8178A is a boost converter that drives LEDs in series. The boost converter runs at 600kHz fixed switching frequency to reduce output ripple, improve conversion efficiency, and allows for the use of small external components. The default white LED current is set with the external sensor resistor Rset, and the feedback voltage is regulated to 200mV, as shown in the typical application. During the operation, A pulse width modulation (PWM) signal can be applied to the CTRL pin through which the duty cycle determines the feedback reference voltage.
