  • Description

    The KA3842S is a fixed-frequency current-mode PWM controller designed for OFF-Line and DC-to-DC converter applications. It requires minimal external components and provides precise duty cycle control. The integrated circuit features a trimmed oscillator, temperature-compensated reference, high-gain error amplifier, current sensing comparator, and a high-current totem pole output, making it ideal for driving a power MOSFET.

    Specifications and features

    • Low Start-Up Current

    • Maximum Duty Cycle

    • Under Voltage Lockout With Hysteresis

    • Operating Frequency Up To 500kHz

    Application Scenarios

    The KA3842S is commonly used in OFF-Line and DC-to-DC converter applications. It is suitable for a wide range of electronic devices that require precise duty cycle control and high-current output.
