SKYWORTH Price The maximum duty cycle under boost mode is internally limited t0 70% to prevent inductor saturation. If the converter is turned on for 100% duty cycle, inductor never gets a chance to discharge its energy and eventually saturate. In boost mode, synchronous rectifier is always turned on for minimum or greater duration as long as the switch has been turned on. The controller will deliver 0% duty cycle, if the input voltage is greater than the programmed output voltage. Because of signal propagation time and MOSFET delay/rise/fall time, controller will not transition smoothly from minimum controllable duty cycle t0 0% duty cycle. For example, controller may decrease its duty cycle from 5% t0 0% abruptly, instead of gradual decrease you see from 70% t0 5%. SKYWORTH on stock Recommended Operating Conditions . Supply voltage VDDb 3.0 t0 5.5 VDDa, VDDC, VDDd 3.0 t0 3.6 VM 0.0 VH 14.5 t0 15.5 VL -7.0 to -8.0 VDDe, VDDf, VDDg 3.0 t0 3.6 . Operating temperature Topr -20 to +75 The PWM frequency can be programmed externally by adding a capacitor from PWM OUT to PWM GND. In addition, multiple PWR-82520X's can be synchronized by using one device as a master and connecting its PWM OUT pin to the PWM IN of all the other slave devices in a system or by applying a SYNC pulse. |
