DPA-Switch, Power Integrations

The DPA-Switch Family combines a 220 V power MOSFET with a controller that provides current monitoring, undervoltage and ovetemperature 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.

Supports flyback and forward topology
Programmable internal current sense eliminates external sense components
Built-in auto-restart for output overload/open loop protection
EcoSmart® Energy Efficiency, extremely low consumption at no-load

The DPA-Switch IC is a highly integrated solution for DC-DC conversion applications with 16-75 VDC input. High performance features are enabled with three user configurable pins. Hysteretic thermal shutdown is also provided. In addition, all critical parameters (i.e. current limit, frequency, PWM gain) have tight temperature and absolute tolerance, to simplify design.

Lossless integrated current limit
Built-in auto-restart
Input UV/OV shutdown protection
Pin selectable 300/400 kHz
DC-DC converter module "bricks"
PoE Powered Devices
Servers, routers & network line cards
Telecom central office equipment
