Self-Excitation Type Semi-Regulated (World

Spec.) Switching Regulator (110W Output)

Overview

The STK730-060 incorporates on-chip all the power switch-

ing, amplifier, error detection and overcurrent protection

circuits required in a self-excitation type semi-regulated

off-line switching regulator. As a result, it can be used in

the design of switching power supplies with minimal num-

ber of external components. Furthermore, the adoption of

MOSFET power switching elements supports a higher os-

cillator frequency than that possible with bipolar transis-

tors. This allows smaller pulse transformers and capacitors

to be used, making it possible to construct miniature power

supply systems.

Applications

• CRT/CTV power supplies

• Office automation equipment power supplies

Features

• Power MOSFET devices

• Ideal for semi-regulated control switching supplies

• Error detection circuit on-chip (40.5 ±0.5V set reference

voltage)

• Overcurrent protection circuit on-chip

• Pin compatible with all other devices in the same series

of devices with 110 to 280W power ratings

• Higher oscillator frequency allows the use of smaller pulse

transformers

• IMST substrate acts as an electromagnetic shield, mak-

ing low-noise designs possible
