Key Features

Multi-Mode Control

The operation mode switching with three steps according to load conditions achieves the optimal high efficiency and low noise power supply systems across the full load range. (The confirmation of product number is necessary because some functions are different in each product.)

In Standby (Under Standby Load Conditions):

UVLO Intermittent Oscillation by lowering output voltage --- Switched by Standby Signal, or

Auto Burst-Oscillation --- Switched Automatically

Under Low to Middle Load Conditions: Bottom-Skip Quasi-Resonant Operation

(Bottom-Skip QR)

Under Middle to Rating (or Heavy) Load Conditions: Quasi-Resonant Operation (QR)

Current-Mode Control

Built-in PWM Oscillator

The PWM operates with the minimum frequency of around 22 kHz, until the quasi-resonant

signal becomes valid, reduces the stress on components at startup and load-shorted.

Soft-Start Function

Step-Drive Function, reducing switching noise

Built-in Maximum ON Time Limitation Circuit The function limits the maximum ON time of power

MOSFET, during the transitions at low input voltage, power ON/OFF.

Input Compensation at Overcurrent The function reduces the distortion of overcurrent operation

point to AC input voltage change by adding three components.

Built-in Avalanche Energy Guaranteed High-Voltage Power MOSFET

Various Protections

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

Overload Protection (OLP)-------------------------------------- Latch Shutdown

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

Application

Switching Power Supplies for Digital Consumer Equipment;

LCD-TVs, PDP-TVs, CRT-TVs, etc., Home Appliances, OA Equipments,

Industry Machines, Communication Devices, Others
