The Cf capacitance required for 1-lsb PWM ripple attenuation is 2 (N-2) Tpwm/R2, where N is number of PWM bits and Tpwm is the PWM period. Since Cf will never see more than perhaps a volt, its voltage ...

The main simplification was using a constant PWM signal ... about 5V come out eventually with some ripple. The ripple isn’t bad at all and the voltage is steady after about 15 ms. I changed ...

This single-chip, highly integrated active-clamp current-mode PWM controller solution is designed ... thermal, under-voltage lockout (UVLO) and over-voltage protection (OVP).

OptiComp’s highly controlled switching frequency avoids the common problems with popular architectures wherein light-load operation introduces unwanted EMI and increased output voltage ripple.
