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_CCvoltage drop

The function improves the startup operation and makes a low V_CCcapacitor applicable.

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
