PKL 4000 I Series 125-200 Watt DC/DC power modules * High efficiency 90% typ. (3.3 V) at full load * High power density, 68 W/in3, (3.3 V at 60 A) * Patent pending Paralleling feature * Fast dynamic response, 200 s, 250 mVpeak typ. * 1,500 V dc isolation voltage * Max case temperature +100 C 61.5 x 61.0 x 12.7 mm (2.42 x 2.4 x 0.5 inch) The PKL 4000 I series represents another one of Ericsson's "industry first" achievements in the continued development of our "third generation" of high-density, high-efficiency power modules. This module packs 68W/in3 at 90% efficiency (3.3 V at 60A) in a half-brick footprint that has been enhanced to include two additional output pins for motherboard connection reliability. These breakthrough features come from using the most advanced patented topology utilizing integrated magnetics and synchronous rectification on a low-resistivity multilayer PCB. This product features fast dynamic response times and low output ripple, which are important parameters when supplying low-voltage logics. The PKL 4000 I series products are intended to be used in 48/60 V dc (36-75 V dc) power systems and are also especially suited for limited board space and high dynamic load applications. The PKL 4000 I series also offers over and undervoltage protection, over-temperature protection, softstart, parallelling capability and is short circuit proof. 14 VI VO/IO max PO max Article Code 36-75 Vdc 2.5 V/50 A 125 W PKL 4119 PI 36-75 V dc 3.3 V/50 A 165 W PKL 4110 PI 36-75 Vdc 2.5 V/60 A 150 W PKL 4119A PI 36-75 V dc 3.3 V/60 A 198 W PKL 4110A PI (c) Ericsson Microelectronics, August 2000
