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 V to 600 V AC AC 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.
