Description for the UCC28710

The UCC2871x family of flyback power supply controllers provides isolated-outputConstant-Voltage (CV) and Constant-Current (CC) output regulation without the use of an opticalcoupler. The devices process information from the primary power switch and an auxiliary flybackwinding for precise control of output voltage and current.

An internal 700-V start-up switch, dynamically-controlled operating states and a tailoredmodulation profile support ultra-low standby power without sacrificing start-up time or outputtransient response.

Control algorithms in the UCC28710 family allow operating efficiencies to meet or exceedapplicable standards. The output drive interfaces to a MOSFET power switch. Discontinuousconduction mode (DCM) with valley switching reduces switching losses. Modulation of switchingfrequency and primary current peak amplitude (FM and AM) keeps the conversion efficiency highacross the entire load and line ranges.

The controllers have a maximum switching frequency of 100 kHz and always maintain controlof the peak-primary current in the transformer. Protection features help keep primary and secondarycomponent stresses in check. The UCC28710 allow the cable compensation to be programmed. TheUCC28711, UCC28712 and UCC28713 devices allow remote temperature sensing using a negativetemperature coefficient (NTC) resistor while providing fixed cable-compensation levels.

Carrier options

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

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.
