Product Summary

The TinySwitch series is a series of power supply ICs from Power Integrations that integrates high-voltage power MOSFETs and control circuits into a single package. Suitable for flyback isolated power supply designs, it allows for the construction of small, highly efficient power supply circuits with fewer external components. The TinySwitch series achieves high-efficiency operation and fast response performance while balancing ease of design and reduced component count. The TinySwitch-5 features an expanded output power range, supporting up to 60W with PCB heat dissipation and up to 190W with an external heatsink.

Furthermore, it maintains high power conversion efficiency even under light load conditions, helping to comply with standby power regulations. It is used in a wide range of applications, including computer standby power supplies, consumer electronics, home appliances, air conditioning equipment, chargers, AC adapters, and auxiliary power supplies for industrial equipment.

Power supply design that excels in the TinySwitch series

■ Power supply design aiming to reduce the number of components
The TinySwitch series integrates high-voltage MOSFETs and control circuits into a single package, contributing to a reduction in external components. Its simplified circuit configuration makes it suitable for power supply designs where miniaturization and reduced mounting area are required.

■ When you want to design a small isolated power supply
This series is suitable for flyback-type isolated power supplies and can be used in applications requiring small power supplies, such as chargers, AC adapters, and auxiliary power supplies for home appliances.

■ Power supply design that prioritizes high efficiency
Because it can achieve high power conversion efficiency even under light load conditions, it is suitable for power supply designs that prioritize efficiency improvement and power consumption reduction.

■ Equipment that requires reduced standby power consumption
The TinySwitch-5 supports low standby power designs by improving efficiency under light loads. It is also suitable for power supply designs of equipment considering compliance with standby power regulations.

■ Power supply design aimed at shortening development time
Because it can be constructed with a small number of components, it contributes to reducing circuit design and evaluation man-hours. It is suitable for applications aiming for rapid product development and improved design efficiency of power supply circuits.
