STEVAL-ISA211V1

STEVAL-ISA211V1 is a flyback converter board designed for industrial or photovoltaic sectors as an auxiliary power supply. The 24V/100W output with reinforced isolation can be used in several applications. The input voltage range starts from standard Europe voltage at 230V AC and extends to 690V AC or 1k VDC. For short-time periods or lower output power, the converter can operate with voltage decreased down to 150V DC. The board is based on the L6566BH multi-mode controller and STW12N170K5 1700V MDmesh K5 Power MOSFET in one-switch flyback topology with isolated output.

• Wide input voltage range: 230 to 690V AC and 250 to 1000V DC input range
• Selectable fixed-frequency or quasi-resonant operation
• Embedded 1kV high voltage startup
• Modified soft-start circuit
• Optional brownout protection
