STEVAL-ISA030V1 6 W 3-phase SMPS for metering evaluation board based on ESBT(R) Data Brief Features Input voltage: 150 VDC - 850 VDC Output power: 6 W Output voltage: CH1: 14 V / 430 mA Switching frequency: >30 kHz Efficiency: >80% Feedback: primary regulation Description The STEVAL-ISA030V1 evaluation board is a complete solution for a 5 W single output SMPS, the type widely used as a power supply in metering applications. The design is based primarily on ST's L6565 PWM driver and the STC04IE170HP as the main switch. The design method can also be applied to an SMPS designed for other applications which work on a threephase mains, and can easily be upgraded for higher output power.
