The LMR36503E-Q1 is a 65V DC/DC, 0.3A buck regulator that features synchronous rectification to achieve high conversion efficiency in a small footprint. The LMR36503E-Q1 evaluation module (EVM) operates over a wide input voltage range of 5.5V to 65V to provide a regulated 5V output up to 0.3A load at 2.2MHz switching frequency. The LMR36503MSCEEVM can support output voltage regulation accuracy better than 1.5% at full load and is adjustable using an external resistor divider.

  • Input voltage range: 5.5V to 65V
  • Output voltage: 12V
  • Load current: 0 to 0.3A
  • Switching frequency: 2.2MHz
  • Adjustable output voltage
  • External synchronization capability
  • Internal spread spectrum capability
  • Selectable pulse-frequency modulation or forced pulse-width modulation at light-load
  • Supports operation up to 150°C ambient
  • Supports other variants of the IC by replacing some components
AC/DC & DC/DC converters (integrated FET)
