Part Number: KJ3842AN

Manufacturer: JC

Specifications:

  • Type: PWM Controller IC
  • Package: DIP-8 (Dual In-line Package, 8-pin)
  • Input Voltage Range: 7V to 35V
  • Output Voltage: Adjustable via external components
  • Switching Frequency: Up to 500kHz (depends on external configuration)
  • Duty Cycle Range: 0% to 100%
  • Operating Temperature Range: -40°C to +85°C

Descriptions:

The KJ3842AN is a pulse-width modulation (PWM) controller IC designed for power supply applications. It provides precise voltage regulation and is commonly used in switch-mode power supplies (SMPS), DC-DC converters, and battery chargers.

Features:

  • Undervoltage Lockout (UVLO): Ensures proper operation within the specified voltage range.
  • Current Limiting: Protects against overcurrent conditions.
  • Soft-Start Function: Reduces inrush current during startup.
  • Error Amplifier: Provides feedback loop stability.
  • Totem Pole Output: Directly drives power MOSFETs or transistors.
  • Low Standby Current: Improves efficiency in standby mode.

This IC is a functional equivalent to the UC3842AN but manufactured by JC.
