STR-A6000 Series
Power IC for PWM Type Switching Power Supply
with Low Noise and Low Standby Power
■ General Descriptions
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.
■ Features
Current-Mode Type PWM Control
Built-in Random Switching Function
DIP-8
The function reduces the EMI noise and enables a simplified (low-cost) EMI filter,
by the slight- random-change of PMW frequency f_OSC.
Auto-Standby Function: The burst-oscillation enables the low standby power. Input Power P_IN < 25mW at no load
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_CC voltage drop
The function improves the startup operation and makes a low V_CC capacitor applicable.
Leading Edge Blanking Function
Slope Compensation Function
Built-in Avalanche Energy Guaranteed High-Voltage Power MOSFET

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.
