ST AN2509 Application note

Update: 30 September, 2023

This application note describes the performances of a 400W reference board, with wide-range mains operation and power-factor-correction (PFC) and presents the results of its bench evaluation. The electrical specification refers to a power supply for general purpose application, with two main output voltages (200 V and 75 V). The main features of this design are the very low no-load input consumption (<0.5 W) and the very high global efficiency, better than 90% at full load and nominal mains voltage (115 - 230 VAC).
