HC2609B is an offline switching power supply chip with a peak output power of 20W. HC2609B integrates a PWM controller, 700V power tube and primary peak current detection circuit. It adopts self-power supply technology, which can omit the auxiliary power supply winding, simplify the peripheral circuit and PCB layout, and is suitable for low-power flyback switching power supply. HC2609B has a temperature control mode to avoid charging interruption during charging.

Features:-

  • Built-in 700V high-voltage power tube
  • Output constant power control
  • Built-in 16mS soft-start circuit
  • Self-powered technology, no need for external auxiliary winding power
    supply
  • Built-in frequency modulation circuit simplifies peripheral EMI
    design costs
  • Complete overvoltage, overtemperature, overcurrent, overload, and
    output open circuit protection
  • Built-in temperature control mode to avoid charging interruption
    during charging
  •  Using SOP8 package
