NCP1562A Datasheet | onsemi

features of the NCP1562 are soft- stop and a cycle skip current limit with a time threshold. Soft- stop circuitry powers down the converter in a controlled manner if a severe fault is detected. The cycle skip detector enables a soft- stop sequence if a continuous overcurrent condition is present. Additional features found in the NCP1562 include line feedforward, frequency synchronization up to 1.0 MHz, cycle- by- cycle current limit with leading edge blanking (LEB), independent under and overvoltage detectors, adjustable output overlap delay, programmable maximum duty cycle, internal startup circuit and soft- start. Features - Dual Control Outputs with Adjustable Overlap Delay - >2.0 A Output Drive Capability - Soft- Stop Powers Down Converter in a Controlled Manner - Cycle- by- Cycle Current Limit - Cycle Skip Initiated if Continuous Current Limit Condition Exists - Voltage Mode Operation with Input Voltage Feedforward - Fixed Frequency Operation up to 1.0 MHz - Bidirectional Frequency Synchronization - Independent Line Undervoltage and Overvoltage Detectors - Accurate Programmable Maximum Duty Cycle Limit - Programmable Maximum Volt- Second Product - Programmable Soft- Start - Internal 100 V Startup Circuit - Precision 5.0 V Reference - These are Pb- Free Devices Typical Applications - Telemunications Power Converters - Low Output Voltage Converters using Control Driven Synchronous Rectifier - Industrial Power Converters - 42 V Automotive System - ATX Power Supplies http://onsemi.
