Manufacturer:IXYS Description:Filtered PWM operation The input of an internal low pass filter is switched to VREF when the EN pin is high and switched to ground when the EN pin is low. The output of this filter drives the comparator within the control loop. A continuous high state on EN therefore provides a filtered voltage of value Vref to the comparator. However, by varying the duty cycle of the EN signal at a suitably high frequency (f>10kHz), the control loop will see a voltage, that has an average value equal to the duty cycle multiplied by VREF. This provides a means of adjusting the output voltage to a lower value. It also allows the device to be both turned on and adjusted with a single signal at the EN pin. The output during this mode of operation will be a dc voltage equal to VREF*(R1+R2)/R1 x duty cycle. |
