Off-Line SMPS Current Mode Controller with integrated 650V CoolMOS ® and Startup cell (frequency jitter Mode) in DIP-8

Product Highlights

• Active Burst Mode to reach the lowest Standby Power Requirements < 100mW

• Adjustable Blanking Window for High Load Jumps to increase Reliability

• Frequency Jittering for Low EMI

• Pb-free lead plating, RoHS compilant

Description

The CoolSET®-F3(Jitter version) meets the requirements for Off-Line Battery Adapters and low cost SMPS for the lower power range. By use of a BiCMOS technology a wide VCC range up to 26V is provided. This covers the changes in the auxiliary supply voltage if a CV/CC regulation is implemented on the secondary side. Furthermore an Active Burst Mode is integrated to fullfill the lowest Standby Power Requirements
