Product Details
The DPA-Switch IC is a highly integrated solution for DC-DC conversion applications with 16-75 VDC input. DPA-Switch uses the same proven topology as TOPSwitch™, cost effectively integrating a power MOSFET, PWM control, fault protection and other control circuitry onto a single CMOS chip. 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 and reduce system cost.
- Monolithic IC integrating 220 V high frequency MOSFET with all control & fault protection circuitry
- Wide DC input voltage range (16 VDC to 75 VDC)
- Lossless integrated current limit
- Built-in auto-restart
- Voltage mode control allows 75% duty cycle while providing >5 kHz loop bandwidth
- Input UV/OV shutdown protection (meets ETSI standards)
- Pin selectable 300/400 kHz
- Enables low cost synchronous rectification
Applications
- 24 V/48 V Distributed Power Architectures (DPA)
- DC-DC converter module "bricks"
- PoE Powered Devices (PoE Applications Support Page)
- Servers, routers & network line cards
- Telecom central office equipment
- VoIP & digital feature phones
- Temperature & industrial controls
