DIGITALLY MANAGED PUSH-PULL ANALOG PWM CONTROLLERS

The 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 the PWM feedback loop with traditional Analog methods, but the UCD8K controllers include circuitry to interpret a time-domain digital pulse train. The pulse train contains the operating frequency and maximum duty cycle limit which are used to control the power supply operation. This eases implementation of a converter with high level control features without the added complexity or possible PWM resolution limitations of closing the control loop in the Discrete time domain.
