높이 = 1.65mm Length = 5mm The HVLED007 is a current-mode PFC controller specific for isolated high power factor, flyback converters operated in transition mode (aka quasi-resonant operation). Targeting both indoor and outdoor solid-state lighting applications, it provides extended temperature range operation down to -40 °C with guaranteed electrical specification. The main feature of this IC is a special circuit (Input Current Shaper, ICS), that enables High-PF quasi-resonant flyback converters to draw a theoretically sinusoidal input current from the power line, unlike the traditional control. In practice, with little effort it is possible to achieve a total distortion of the input current (THD) lower than 10% at full load and lower than 20% at 30% load over the entire input voltage range.The IC is provided with a control input intended for being driven by the phototransistor of an optocoupler to close a secondary-regulated isolated control loop. However, with the addition of a simple external circuitry it can be used to close a primary-regulated voltage loop as well.
