57W Output Synchronous Buck Converter for Telecom Reference Design


Design files


PMP20178 is a voltage-mode synchronous buck converter reference design rated for 5.2V output at 11A from an input voltage of 15V to 60V. This design uses the LM5145 synchronous buck controller at a switching frequency of 200 kHz. Features include power good, synchronization and trim functions.

  • 57W continuous output power
  • Voltage-mode control with line feedforward
  • MOSFET current sensing
  • Power good flag
  • Synchronizable to external clock
