Description

• Parameters: TRANSITION-MODE PFC CONTROLLER
• Description: SD7528 is a high performance transition-mode power factor correction (PFC) controller. SD7528 includes a highly linear multiplier, able to reduce AC input current distortion. The output voltage is controlled by means of a voltage-mode error amplifier and a precise internal voltage reference. Download the latest English version SD7528 Brief Datasheet
• Features: SD7528 includes a disable function suitable for IC remote ON/OFF. An effective two-step OVP enables to safely handle over-voltage either occurring at start-up or resulting from load disconnection. High-performance linear multiplier Zero current detector Built-in restart timer Integrate digital LEB Precision adjustable overvoltage protection Disable function Low start-up current (15μA) Low quiescent operating current (3.0mA)
• Applications: Amplifier
