LM5019 Isolated Bias Supply Evaluation Board


Order now


The LM5019ISOEVAL evaluation board facilitates evaluation of the LM5019 100V, 100mA Constant On-Time Synchronous Buck Regulator. An isolated bias supply is implemented in this evaluation board with the LM5019 the Constant On-Time regulator. The LM5019 regulator integrates both the high and low side power switches essential for creating an isolated buck converter.

  • Input Voltage Range: 20V to 100V
  • Primary Output Voltage: 10V
  • Secondary (Isolated) Output Voltage: 9.5V
  • Maximum Load Current (Primary and Secondary): 100 mA
  • Maximum Power Output: 1W
  • Nominal Switching Frequency 750 kHz efficiency (FIN = 24V, IOUT2 = 100mA
  • 70% Board Size: 2 inch x 2 inch
