Precise PWM generation supports phase-cut dimming and power factor correction. In Figure 1 we see the problems in driving these LEDs directly off of the AC line. The dimming control interface of the LM3463 accepts both analog and PWM dimming control signals. LEDs such as the Everlight HiVo series have Vf ranges to accommodate 110 Vac and 220 Vac voltages. navigate to this website
This adds complexity and cost to the driver, often adding entire power stages to convert the high PFC voltage to LED current. Lastly, since the majority of dimmers (TRIAC or electronic) operate by chopping the AC waveform supplied to the lamp, dimming only occurs during the brief period the lamps are conducting. Using linear dimming, the output current of the HV9910DB1 can be lowered to about 0.01A (note: zero output current can be obtained only by PWM dimming). Together, they ensure interoperability, rapid development and robust board design.UTC2000 Microchip's strong brand name and expertise in USB solutions is demonstrated yet again with the UTC2000.
