Constant Output Current: o HV9921 – 20mA o HV9922 – 50mA o HV9923 – 30mA Universal 85-264VAC Operation Fixed OFF-Time Buck Converter www.DataSheet4U.com Internal 500V Power MOSFET General Description The HV9921/22/23 are pulse width modulated (PWM) high-efficiency LED driver control ICs. They allow efficient operation of LED strings from voltage sources ranging up to 400VDC. The HV9921/22/23 include an internal high voltage switching MOSFET controlled with fixed off-time TOFF of approximately 10µs. The LED string is driven at constant current, thus providing constant light output and enhanced re... |
