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
