Descrição
DK124 is an offline switching power supply IC with a maximum output power of 24W. Unlike solutions combining a PWM controller with external discrete power MOSFETs, the DK124 integrates a PWM controller, 700V power transistor, and primary-side peak current sensing circuit on-chip. It also employs a patented self-supply technology that eliminates the need for an auxiliary winding, greatly simplifying the peripheral application circuit and reducing component count, board size, and weight. It is particularly suited for cost-sensitive flyback switching power supplies.
Recursos
- Universal voltage input 85V–265V
- Built-in 700V high-voltage power transistor
- Integrated high-voltage startup circuit, no external startup resistor required
- Built-in 16mS soft-start circuit
- Built-in high/low voltage power compensation circuit for consistent maximum output power across input voltage range
- Patented self-supply technology, no external auxiliary winding required
- Built-in frequency modulation circuit, simplifies peripheral EMI design cost
- Comprehensive OVP, OTP, OCP, overload, and output open/short-circuit protection
Aplicações
- DVD, VCR, STB power supplies
- Adapter and charger power supplies
- LED power supplies
