STEVAL-ISA211V1 100 W, Ultra-Wide Range Flyback Converter Based on L6566BH


The STEVAL-ISA211V1 flyback converter is designed for industrial or photovoltaic sectors to be used as an auxiliary power supply. The STEVAL-ISA211V1 is based on the L6566BH multi-mode controller and STW12N170K5 1700 V MDmesh K5 Power MOSFET, in one-switch Flyback topology with isolated output. L6566BH integrates 840 V high voltage startup which is boosted by the STD1NK60T4 Power MOSFET up to 1 kV.

The 24 V/100 W output with reinforced isolation can be used in several applications. The input voltage range starts from standard Europe voltage (230 VAC) and ends at 690 VAC or 1 kVDC. For short-time periods or lower output power, the converter can operate with voltage decreased down to 150 VDC. The converter operates in fixed-frequency mode, but it can be easily set to quasi-resonant mode by changing one resistor.

Features and Benefits


Wide input voltage range: 230 to 690 VAC, 250 to 1000 VDC

Output 24 V/100 W

Short time undervoltage (long time for 50 W output) down to 150 VDC/180 VAC

Selectable fixed-frequency or quasi-resonant operation

Embedded 1 kV high voltage startup

Modified soft-start circuit

Optional brownout protection

RoHS compliant

Applications


The STEVAL-ISA211V1 flyback converter is ideal for applications that require a reliable and energy efficient Auxiliary SMPS or Industrial Power Supply. This versatile flyback converter helps to prevent downtime and is suited to industrial or photovoltaic sectors.
