The CS51021AEDR16G is a fixed frequency, current mode PWM controller designed by On Semiconductor for AC-DC or DC-DC primary side control applications. It integrates several features to reduce external component count, including low startup current, high frequency operation capability, overvoltage and undervoltage monitoring, and externally programmable dual threshold overcurrent protection.
Key electrical specifications include a maximum startup current of 75 µA and a switching frequency of 1.0 MHz. The device supports a wide operating voltage range of 7.7 V to 20 V and features a 1.0 A sink/source gate drive. It offers programmable soft start, accurate maximum duty cycle limit, programmable slope compensation, and leading edge current sense blanking.
This controller is housed in a 16-lead narrow body SOIC package, suitable for surface mounting. Its bidirectional synchronization capability and integrated features make it a versatile solution for various power supply designs. The operating temperature range is -40°C to 85°C (TA).
The CS51021AEDR16G provides undervoltage and overvoltage protection monitors, along with programmable dual threshold overcurrent protection with delayed restart. It also features an externally available 5.0 V reference and 50 ns PWM propagation delay.
