Features & Benefi ts
The DPA-Switch Family combines a 220 V power MOSFET with a controller that provides current monitoring, undervoltage and over
temperature protection, soft start and other control functions in a single device, saving up to 30 external components in the power supply
design. Combining the key switching elements into a single package reduces design complexity and ensures rapid, low-risk development of
highly cost-effective power supplies.
Superior Performance and Flexibility. The DPA-Switch family supports a range of power requirements in either forward or fl yback
topologies and offers a variety of package options to maximize design fl exibility. A DIP-8 package is available for low-cost designs, and a
thermally effi cient TO-263-7C R package (2 °C/Watt) is available for higher power applications.
