Description

Overview

The STK730-060 incorporates on-chip all the power switching, 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 number of external components. Furthermore, the adoption of MOSFET power switching elements supports a higher oscillator frequency than that possible with bipolar transistors. This allows smaller pulse transformers and capacitors to be used, making it possible to construct miniature power supply systems.

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, making low-noise designs possible

Applications

• CRT/CTV power supplies

• Office automation equipment power supplies
