ACP2766 - Boost WLED Driver

General Description

The ACP2766 is a step-up DC-DC converter which operating as current source to drive white LEDs.

The light intensity of LEDs is proportional to the current passing through them.

The default white LEDs current is set with the external resistor, and the feedback voltage reference is set to 200mV.

Key Features

open LED protection function that can disable the chip to prevent the output voltage from exceeding voltage rating during open LED conditions. . ◤.

ACP2766 TSOT26,Boost WLED Driver with 38V OVP ◤GENERAL DESCRIPTION The ACP2766 is a step-up DC-DC converter which operating as current source to drive white LEDs. The light intensity of LEDs is proportional to the current passing through them. The default white LEDs current is set with the external resistor, and the feedback voltage reference is set to 200mV. During the operation, the LED current can be pulsed by adding a PWM signal to the chip, through which the duty cycle changes the feedback reference voltage. With fixed frequency of 1.2MHz, ACP2766 is allowed using tiny inductor and capacitors to minimize the footprint.
