General Descriptions
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 conditions. The product
achieves high cost-performance power supply systems with few external components.
Features
Applications
Product Lineup
The STR-A6000 series products are power ICs for switching power supplies,
Current-Mode Type PWM Control
Built-in Random Switching Function
The function reduces the EMI noise and enables a simplified (low-cost) EMI filter,
by the slight- random-change of PMW frequency f
Auto-Standby Function: The burst-oscillation enables the low standby power. Input Power P
Built-in Startup Circuit, enabling low power consumption
Brown-In / Brown-Out Function
The function enables the oscillation start/stop by externally rated input voltage and makes protections at low input
voltage.
Overcurrent Protection (OCP) with Built-in Input Compensation Circuit:
The protection has less AC input voltage dependency.
Overload Protection (OLP) with Built-in Delay Timer
High Speed Latch Release Function
The function releases the latch immediately at AC supply OFF, after the latch protection operation.
Bias-Assist Function, reducing Operating V
The function improves the startup operation and makes a low V
Leading Edge Blanking Function
Slope Compensation Function
Built-in Avalanche Energy Guaranteed High-Voltage Power MOSFET
Various Protections
Battery Chargers; Mobile Phones, Digital Cameras, Camcorders, Electric Shavers, Emergency/Inducement Lights etc.
Standby Power Supplies; LCD-TVs, PDP-TVs, Desk-Top PCs, LBPs, Audio Equipment, etc.
Small SMPSs; Ink Jet Printers, BD/DVD Players, CD Players, Set-Top-Boxes, etc.
Auxiliary Power Supplies for Controllers; Air Conditioners, Refrigerators, Washing Machines, Dish Washers, etc
Overcurrent Protection (OCP)--------------------------------- Pulse-by-Pulse
Overload Protection (OLP) ------------------------------------ Auto-Restart
Overvoltage Protection (OVP) -------------------------------- Latch Shutdown
Thermal Shutdown Protection (TSD) ------------------------ Latch Shutdown
Note 1: The maximum output power is derived from thermal specifications. The actual output power may be
