Product Folder Order Now Technical Documents Tools & Software Support & Community UCD8220 SLUS652E * MARCH 2005 * REVISED APRIL 2.
The UCD8220 analog pulse-width modulator (PWM) device is used in digitally managed power supplies using a microcontroller or the TMS320 DSP family.

UCD8220 Features

* 1 For digitally managed power supplies using μCs or the TMS320 ™ DSP family
* Voltage or peak current mode control with cycleby-cycle current limiting
* Clock input from digital controller to set operating frequency and max duty cycle
* Analog PWM comparator

UCD8220 Applications

* Digitally managed switch mode power supplies
* Push-pull, half-bridge, or full-bridge converters
* Battery chargers Systems using the UCD8220 device close the PWM feedback loop with traditional analog methods, but the UCD8220 controller includes circuitry to interpret a ti
