SCM1710A Description
This highly integrated SCM1710A current model PWM controller is ideal for offline AC-DC converter designs. The chip’s accurate operating frequency is achieved by trimming, its maximum switching frequency can be set by means of external resistor values. In case of a light load condition, the chip decreases the operating switching frequency as well as the CS peak current.
