Product Summary
The STR-W6053S is a power IC for switching power supplies, incorporating a power MOSFET and a current-mode type PWM controller IC. The low standby power is accomplished by the automatic switching between the PWM operation in normal operation and the burst-oscillation under light load condition. The STR-W6053S achieves high cost-performance power supply systems with few external components. The applications of the STR-W6053S include Home Appliances (White Goods), Digital Consumer Equipment, OA Equipment, Industry Machines, Communication Devices, Others.
Features
STR-W6053S features: (1)Current-Mode Type PWM Control; (2)PWM with Jittering Function The function reduces the EMI noise and enables simplified (low-cost) EMI filters. The jittering period is adjustable by an external capacitor; (3)Auto-Standby Function, The burst-oscillation enables the low standby power. Input Power PIN < 100mW at no load; (4)Built-in Startup Circuit, enabling low power consumption; (5)Overcurrent Protection (OCP) with Built-in Input Compensation Circuit. The function has less AC input voltage dependency; (6)Overload Protection (OLP) with Built-in Delay Timer ( the delay time is adjustable by an external capacitor); (7)External Latch Protection (ELP). The function enables the latch shutdown by external signal; (8)Bias-Assist Function, reducing operating VCC voltage drop. The function improves the startup operation and makes a low VCC capacitor applicable; (9)Leading Edge Blanking Function; (10)Slope Compensation Function; (11)Built-in Avalanche Energy Guaranteed High-Voltage Power MOSFET.
