TinySwitch

The TinySwitch families of products combine a high-voltage power MOSFET with a flyback power supply controller. The latest generation, TinySwitch-5, expands the output power range to allow designs of up to 60 W without a heatsink and 190 W with a heatsink. It realizes higher than 88% efficiency in 12 W universal designs and maintains a flat efficiency over the entire load range with an extremely fast transient response. 

Designs using TinySwitch-5 ICs can easily meet ErP regulations by allowing more than 200 mW of available power under the new 300 mW stand-by input limit. 

The external circuitry accompanying TinySwitch is simple to design, and power sub-systems using the TinySwitch product are relatively insensitive to component tolerances due to manufacturing variances, aging and operating temperature.

TinySwitch devices are used in a wide range of applications requiring accurate CV or CV/CC operation, including bias supplies for computers, consumer audio/video products, appliance and air conditioning bias supplies, chargers and adapters, and various industrial power sub-systems, including metering and controls.
