Description

General part information

UCD8220 Series

The UCD8220-Q1 analog pulse-width modulator (PWM) device is used in digitally managed power supplies using a microcontroller or the TMS320 DSP family.

The UCD8220-Q1 device is a double-ended PWM controller configured with push-pull drive logic.

Systems using the UCD8220-Q1 device close the PWM feedback loop with traditional analog methods, but the UCD8220-Q1 controller includes 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. The device circuitry 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.
