Application Scenarios & Design Considerations

Mobile Multi-Output PWM Controller with Virtual Current SenseTM

Alternative Part Number

  • LM3478MM --: Widely available low-side N-channel controller in an MSOP-8 package, functionally similar to the SC1403 boost/controller family and easy to source as a drop-in design alternative.
  • TPS40210DGQR --: Boost/flyback controller with wide input range and MSOP PowerPAD package, offering comparable control functionality with better availability and documentation.
  • NCP3063DR2G --: Versatile boost/buck/inverting switching regulator in SOIC-8, suitable as a lower-cost, widely stocked alternative for similar power-supply control applications.
  • MC34063ADR2G --: Versatile DC-DC switching regulator controller covering boost, buck, and inverting topologies; very common and cost-effective substitute for general power conversion.
  • LT1932ES6 --: Compact constant-current boost converter IC suitable for similar power supply designs, offering reliable performance from a well-known vendor.
  • MC34063A --: Classic general-purpose DC-DC switching regulator controller covering boost, buck, and inverting topologies; very common and low cost, suitable when exact SC1403 features are not critical.
  • LT1930ES5 --: Compact high-frequency boost converter in SOT-23-5 that can replace the SC1403 in many step-up applications with fewer external components and good availability.
