6 / 53 page CSTE(max) D _ PK(max) IPK V I R UCC28910 UCC28911 SLUS769C – JULY 2013 – REVISED MARCH 2015 www.ti.com Detailed Pin Description (continued) 7.1.4 IPK (Set the Maximum DRAIN Current Peak) A resistance (RIPK) connected between IPK pin and GND sets the maximum value of the power FET peak current, ID_PK(max). A current, ISENSE, proportional to the power FET current, comes out from the IPK pin during power FET on time. The voltage across RIPK is fed to the PWM comparator and establish to switch off the power FET according to the following equation: where • VCSTE(max) is the equivalent current sense threshold (see Electrical Characteristics table). (3) If the IPK pin is shorted to GND (RIPK = 0), the peak current is automatically set to ID_PEAK(max), 600 mA for UCC28910, or 700 mA for UCC28911. A test is performed at device start up to check whether the IPK pin is shorted to GND or the RIPK is present. If RIPK is less than RIPK_SHORT (maximum), the device interprets it as a short (RIPK = 0) and the DRAIN peak current is set to ID_PEAK(max). Otherwise, if RIPK is greater than RIPK(min) (minimum), the device sets the peak current DRAIN according to the previous equation. A value of RIPK that is in between the before said values is not allowed since the value of the peak current may be selected using either of the two sense resistances: the internal sense resistance and RIPK. 7.1.5 DRAIN The DRAIN pin is connected to the DRAIN of the internal power FET. This pin also provides current to the high voltage current source at start up. 6 Submit Documentation Feedback Copyright © 2013–2015, Texas Instruments Incorporated Product Folder Links: UCC28910 UCC28911 |
