AL1788

LOW STANDBY POWER PFC CONTROLLER

Description

Pin Assignments

The AL1788 is a high performance AC/DC Power Factor Correction

(PFC) controller targeting at LED lighting applications. Based on

Primary Side Regulation (PSR) implementation, AL1788 does not

require opto-coupler and any secondary feedback circuit to save overall

BOM cost. It operates at Quasi-Resonant (QR) mode where MOSFET

is turned on at the valley of the drain voltage, which minimizes switching

loss to result in high efficiency.

With either Flyback or Buck topology, AL1788 system supports high

efficiency, high Power Factor (PF>0.9) and low Total Harmonic

Distortion (THD <20%) for universal input at wide loading range (50%

loading to 100% loading)

COMP

The AL1788 features low start-up current, low operation current and low

standby power. It has rich protection features including Over Voltage

Protection (OVP), Short Circuit Protection (SCP), Over Current

Protection (OCP) and Over Temperature Protection (OTP).

Applications

The AL1788 is available in SOT26 (SC74R) package for the controller.
