Description for the UCD8220-Q1

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.

The UCD8220-Q1 device can be configured for either peak current mode or voltage mode control. The device 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 output circuit architecture, which delivers rated current of ±4-A into the gate of a MOSFET. Finally the device 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-Q1 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 the PowerPAD™ integrated circuit package HTSSOP.

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

A custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships tube or tray devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
