PKL 4119A PI/PKL 4119 PI Advanced Specification 50-60A DC/DC Power Modules 48V Input, 2.5V Output * * * * * * * * * High efficiency 88% Typ (50A) at full load High power density, 51.7 W/in3, (2.5V @ 60A) Fast dynamic response, 200s, +- 200 mVpeak Typ Low output ripple, 80 mVp-p Typ Parallelable with no external components Wide input voltage range (36-75V) 1,500Vdc isolation voltage Max case temperature +100C Designed to meet UL 1950 and EN 60950 The PKL 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 51.7 W/in3 at 87% efficiencies (2.5V @ 60A) in an industry standard 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 series also is especially suited for limited board space and high dynamic load applications. Ericsson's PKL Power Module has been designed with the converging "New Telecoms" market in mind, by specifying the input voltage range in accordance with ETSI specifications. The PKL series also offers over-voltage protection, under-voltage protection, over-temperature protection, soft-start, and is short circuit proof. These modules are manufactured on highly automated manufacturing lines. Ericsson's world-class quality commitment is reflected in our standard five-year warranty. Ericsson Microelectronics has been an ISO 9001 certified supplier since 1991. For a complete product program, please reference the back cover.
