STEVAL-ISA019V3 80 W ESBT quasi-resonant wide-range SMPS demonstration board based on the L6565 for 3-phase applications Data brief Features ■ 3-phase 80 W auxiliary output SMPS ■ Quasi-resonant SMPS ■ Input: 180 VAC to 600 VAC ■ Output voltage: 24 V, 3.3 A ■ Maximum output power: 80 W ■ Efficiency > 80 % ■ Switching frequency > 50 kHz ■ Safety compliant according to EN60950 ■ Feedback: secondary regulation ■ RoHS compliant STEVAL-ISA019V3 Description The STEVAL-ISA019V3 demonstration board is a 3-phase auxiliary power supply with an 80 W dual output SMPS, using the L6565 PWM driver and the STC04IE170HP ESBT as the main switch. The combination of these ST parts provides a high-efficiency solution for high DC input voltage, a typical requirement of any 3-phase application. The necessity to handle both high output power and wide input voltage is resolved using a flyback stage working in mixed operation mode: discontinuous and continuous.
