The DPA-Switch IC family 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.
Applications:
- PoE applications, VoIP phones, WLAN, security cameras
- Telco central office equipment: xDSL, ISDN, PABX
- Distributed power architectures (24 V/48 V bus)
- Industrial controls
Features:
- Highly integrated DC-DC converter ICs for power over Ethernet and telecom applications
- Superior performance and flexibility EcoSmart™ energy efficient
- Built-in auto-restart for output overload/open loop protection
- Fully integrated soft-start for minimum stress/overshoot
- Externally programmable current limit, source connected tab reduces EMI
