Digitally Assisted Push Pull PWM Controller

The UCD8220 Analog pulse-width Modulator device is used in digitally managed power supplies using a Microcontroller or the TMS320? DSP family. UCD8220 ia a double-ended PWM Controller configured with push-pull drive Logic Systems using the UCD8220 device close the PWM feedback loop with traditional Analog methods, but the UCD8220 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.
The UCD8220 CAN be configured for either peak current mode or voltage mode control. It provides a programmable current limit function and a digital output current limit flag which CAN be monitored by the host controller to set the current limit operation. For fast switching speeds, the output stage uses the TrueDrive? architecture, which delivers rated current of 4 A into the Gate of a MOSFET Finally it also includes a 3.3-V, 10-mA linear Regulator to provide power to the digital controller or act as a reference in the system.
The UCD8220 controller is compatible with the standard 3.3-V I/O ports of UCD9K digital power controllers, DSPs Microcontrollers or ASICs and is offered in PowerPAD? HTSSOP and QFN packages.
