UCD8220 and UCD8620 are members of the UCD8K family of analog pulse-width modulator devices to be used in digitally managed power supplies using a microcontroller or the TMS320™ DSP family. UCD8220 and UCD8620 are double-ended PWM controllers configured with push-pull drive logic. The UCD8620 has a 110-V high-voltage startup circuit which can directly start up the controller from a 48-V telecom input line. Systems using UCD8K devices close to 100% of the switching frequency range (i.e., 10 kHz to 2 MHz) and 1µA to 2A of output current, enabling high efficiency and performance.
