Description
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.
Product Highlights
Highly Integrated Solution
? Eliminates up to 50 external components–saves space, cost
? Integrates 220 V high frequency MOSFET, PWM control
? Lower cost plastic DIP surface mount (G package) and through-hole (P package) options for designs ≤35 W
? Thermally efficient TO-263-7C (R package) option for high power applications
Superior Performance and Flexibility
? Eliminates all external current sensing circuitry
? Built-in auto-restart for output overload/open loop protection
? Pin selectable 300/400 kHz fixed frequency
? Wide input (line) voltage range: 16-75 VDC
? Externally programmable current limit
? Source connected tab reduces EMI
? Line undervoltage (UV) detection: meets ETSI standards
? Line overvoltage (OV) shutdown protection
? UV/OV limits gate drive voltage for synchronous rectification
? Fully integrated soft-start for minimum stress/overshoot
? Supports forward or flyback topology
? Cycle skipping: regulation to zero load without pre-load
? Hysteretic thermal shutdown for automatic fault recovery
? RoHS compliant P and G package options
EcoSmart?– Energy Efficient
? Extremely low consumption at no-load
? Cycle skipping at light load for high standby efficiency
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
