概要

概要

The STEVAL-ISA211V1 flyback converter is designed for industrial or photovoltaic sectors to be used as an auxiliary power supply.

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 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 converter operates in fixed-frequency mode but it can be easily set to quasi-resonant mode by changing one resistor.

  • 特徴

    • 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
