An isolated bias supply is implemented in this evaluation board with an LM25017 Constant-On-Time regulator. The LM25017 regulator integrates both the high and low side power switches essential for creating an isolated buck converter.
- Wide Input Voltage (15-48VDC)
- Primary non-isolated 5V output plus Secondary isolated 4.5V output.
- Nominal Switching Frequency 500KHz
- Maximum Load (Primary + Secondary): 600mA or 3W.
- Efficiency (Vin=24V, Iout2=300mA): 75%
