Description

The LM5085 evaluation board provides the design engineer with a fully functional buck regulator, employing the LM5085 PFET switching controller which uses the constant on-time (COT) operating principle. The evaluation board provides a 5V output over an input range of 5.5V to 55V. The circuit delivers load currents to 4.5A, with current limit set at 7.6A. The board is populated with all components except C5.

Features
  • Input Voltage: 5.5V to 55V, 60V maximum
  • Output Voltage: 5V
  • Maximum load current: 4.5A for VIN >8V
  • Minimum load current: 0A
  • Current Limit Threshold: 7.6A
  • Measured Efficiency: 97.2% (VIN 5.5V, IOUT = 0.6Amps)
  • Nominal Switching Frequency: 300 kHz
  • Size: 3.1 in. x 1.5 in. x 0.78 in
