DK2649CB : The DK2649CB is a secondary side flyback type PWM (Pulse Width Modulation) Mode Power Controlli ng IC with high performance and low standby power. With integrated 650V high voltage MOSFET, it is suitable for applications of power supply within 20W output. Under no-load or light load, it works in green mode to reduce the switching loss and improve the working efficiency. The hopping frequency of is set at 25kHz, which can effectively avoid audio noise during operation. The integrated totem-pole driving structure in the chip can effectively improve the EMI characteristics of the application and the s oft start control of the switch. 2. APPLICATIONS ·Mobile phone charger, PD charger ·DVB power.
