Strong Island Posted July 14, 2016 Posted July 14, 2016 Hey guys, does anyone know the vr_ready pin for this ic for epower mod. px3544 was pin 15. Want to do a 8800gtx epower mod. Thanks. PX3540 datasheet, PX3540 PDF, Graphics Processor Digital Multiphase Controller - Primarion Quote
Calathea Posted July 16, 2016 Posted July 16, 2016 I've seen some people desolder the whole IC, maybe that could work. Quote
nachtfalke Posted July 17, 2016 Posted July 17, 2016 (edited) primarion PX3540 it has same configuration pin out like PX3544 , so p_good/vr_ready is same pin 15. VDD(3.3v) is pin36 GND is pin 25 vr_ready pin15 OCP per phase: phase4 pin 28( NC on px3540 and 8800GTS 640/320mb) phase3 pin 31 phase2 pin 34 phase1 pin 38 PX3544 can be used in DC-DC converters up to 130A and 1 to 4 phase pwm PX3540 can be used in DC/DC converters up to 200A up to six phase digital multiphase controller. also PX3544 it has more features like oldest PX3540 -Multiple Internal and External Temperature Limits -Configurable latched fault or autonomous recovery shutdown -Single +3.3V supply operation Edited July 17, 2016 by nachtfalke Quote
