For Digitally Managed Power Supplies Using  
μCs or the TMS320 ™ DSP Family  
DESCRIPTION  
The UCD8220-Q1 analog pulse-width modulator  
device is used in digitally managed power supplies  
using a microcontroller or the TMS320 DSP family.  
Voltage or Peak Current Mode Control with  
Cycle-by-Cycle Current Limiting  
Clock Input from Digital Controller to Set  
Operating Frequency and Max Duty Cycle  
UCD8220-Q1 is a double-ended PWM controller  
configured with push-pull drive logic.  
•
•
•
Analog PWM Comparator  
2-MHz Switching Frequency  
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. 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.
