The DPA424PN is a highly integrated solution DPA-Switch Converter IC for DC-to-DC conversion applications with 16 to 75VDC input. DPA-switch uses the same proven topology as TOPSwitch? 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 and it eliminates up to 50 external components saves space. Hysteretic thermal shutdown is also provided. In addition, all critical parameters have tight temperature and absolute tolerance.
Eliminates all external current sensing circuitry
Built-in auto-restart for output overload/open loop protection
Externally programmable current limit
Source connected tab reduces EMI
Line under-voltage (UV) detection - Meets ETSI standards
Line over-voltage (OV) shutdown protection
UV/OV limits gate drive voltage for synchronous rectification
Fully integrated soft-start for minimum stress/over-shoot
Supports forward or flyback topology
Cycle skipping - Regulation to zero load without pre-load
