STR-A6000 Series

Power IC for PWM Type Switching Power Supply

with Low Noise and Low Standby Power

■

■

■

The STR-A6000 series products are power ICs 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 conditions. The product

achieves high cost-performance power supply systems with few external components.

Current-Mode Type PWM Control

Built-in Random Switching Function

The function reduces the EMI noise and enables a simplified (low-cost) EMI filter,

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.

Leading Edge Blanking Function

Slope Compensation Function

Built-in Avalanche Energy Guaranteed High-Voltage Power MOSFET

Various Protections

Overcurrent Protection (OCP)--------------------------------- Pulse-by-Pulse

Overload Protection (OLP) ------------------------------------ Auto-Restart

Overvoltage Protection (OVP) -------------------------------- Latch Shutdown

Thermal Shutdown Protection (TSD) ------------------------ Latch Shutdown

Battery Chargers; Mobile Phones, Digital Cameras, Camcorders, Electric Shavers, Emergency/Inducement Lights etc.

Note 1: The maximum output power is derived from thermal specifications. The actual output power may be

available around 120 –140% of the above values, respectively, but may be limited by ON duty setting on

transformer design or lower output voltage.
