  • Description

    The AP3844 is an integrated circuit (IC) chip that belongs to the fixed frequency current-mode PWM controller series. This high-performance component is designed with a low start-up current of 50µA to ensure efficient power consumption. It has a robust VREF line/load regulation with low line regulation and low load regulation of 4mV.

    Specifications and features

    • Operating Frequency: Up to 500KHz
    • PWM Frequency Stability over a Full Temperature Range: 2.5%
    • PWM Frequency Stability under a Full Supply Voltage Range: 0.2%
    • Over-temperature Protection with Hysteresis
    • UVLO with Hysteresis

    Application Scenarios

    The AP3844 IC chip is ideally suited for various applications:

    • Off-line Converter
    • DC-DC Converter
    • Voltage Adapter
    • CRT Monitor Power Supply
    • Desktop Power Supply
