Data Brief
Features
Input voltage: VIN: 88 - 265 Vac frequency: 50-60 Hz Output voltage: VOUT = 9 V Output current: IOUT = 5.5 A (6 A peak) Efficiency: >75% Safety: EN60950 compliant Conducted EMI: EN55022
Description
The STEVAL- ISA032V1 forward converter demonstration board is a power supply based on the primary controller L5991 and the STP10NK60Z N-channel 600 V power MOSFET. It is designed to be suitable to supply power to the electronic fiscal cash register (EFCR) demonstration board STEVAL-IPC001V1. The STEVAL- ISA032V1 demonstration board accepts a wide range of input voltage (88 to 265 Vac) and delivers a single 9 V output with a power capability of up to 50 W continuous, and 60 W peak, making it also capable of providing power to a thermal printer.
