SA7527 Datasheet

Part Number SA7527
Manufacturers Silan Microelectronics
Logo Silan Microelectronics
Description POWER FACTOR CORRECTION CONTROLLER
Datasheet SA7527 DatasheetSA7527 Datasheet (PDF)

SA7527 POWER FACTOR CORRECTION CONTROLLER OF CRITICAL DUCTING DESCRIPTION The SA7527 provides simple and high performance active power factor correction. The SA7527 is optimized for electronic ballasts and low power and high-density power supplies which require minimum board size, reduced external components and low power dissipation. Because the R/C filter is included in the current sense block, the external R/C filter is not necessary. Special circuitry has also been added to prevent no load r.

POWER FACTOR CORRECTION CONTROLLER

SA7527 POWER FACTOR CORRECTION CONTROLLER OF CRITICAL DUCTING DESCRIPTION The SA7527 provides simple and high performance active power factor correction. The SA7527 is optimized for electronic ballasts and low power and high-density power supplies which require minimum board size, reduced external components and low power dissipation. Because the R/C filter is included in the current sense block, the external R/C filter is not necessary. Special circuitry has also been added to prevent no load runaway conditions. Regardless of the supply voltage, the output drive clamping circuit limits the overshoot of the power MOSFET gate drive. It greatly enhances the system reliability.
