PWM output voltage scaling reference design for enterprise systems


This reference design shows a buck converter with adjustable output voltage using the TLV62569. The voltage can be adjusted with a PWM signal scaling an output voltage from 2.5 V through 4.3 V. The output voltage adjustment is achieved with a PWM signal in this reference design at a frequency of 20 kHz and a maximum clocking frequency of 10 MHz.
