ON Semiconductor CS51021A CS51022A CS51023A CS51024A handbook

Update: 01 October, 2023

This datasheet is about CS51021A/2A/3A/4A fixed frequency PWM current mode controller, which provides all necessary features required for AC-DC or DC-DC primary side control. The family includes several features to eliminate the additional components needed to implement them externally. In addition to low start-up current (75µA) and high frequency operation capability, the CS51021A/2A/3A/4A family includes overvoltage and undervoltage monitoring, externally programmable dual threshold overcurrent protection, current sense leading edge blanking, current slope compensation, accurate duty cycle control and an externally available 5.0 V reference. The CS51021A and CS51023A feature bidirectional synchronization capability, while the CS51022A and CS51024A offer a sleep mode with 100µA maximum IC current consumption. The CS51021A/2A/3A/4A family is available in a 16 lead narrow body SO package.
