PKJ 4000 I Series 22-150 Watt DC/DC power modules * High efficiency 93% typ. at 12 V * MTBF > 3 million hours in accordance with Bellcore TR-332 * Industry standard footprint * Max case temperature +100 C * 1,500 V dc isolation voltage * High power density, up to 55 W/in3. 61.0 x 57.9 x 12.7 mm (2.4 x 2.28 x 0.5 inch) The PKJ 4000 I series represents a "third generation" of high density DC/DC power modules providing more than 90% efficiency. To achieve this high efficiency they use proprietary drive and control circuits with planar magnetics and low resistivity multilayer PCB technology, and a patent pending topology with active rectification. The PKJ 4000 I series can be used without bulky and height consuming heatsinks, resulting in a lower total cost. This also provides narrow board spacing for electronic, shelf based applications. The products are in the industry standard package size and offer a beneficial alternative to competing products on the market. The PKJ 4000 I series also offers the flexibility of using a heatsink when needed, enabling reduced airflow, extended reliability or higher ambient temperature operation in a wide range of 48 and 60 V dc (36-75 V dc) systems. Similar to other Ericsson power modules, the PKJ 4000 I series includes over and under-voltage protection, over-temperature protection, soft-start and is short circuit proof. 12 VI VO/IO max PO max Article Code 36-75 V dc 1.5 V/15 A 22.5 W PKJ 4218 PIOAT 36-75 Vdc 1.8 V/15 A 27 W PKJ 4218 PIT 36-75 Vdc 2.5 V/15 A 37.5 W PKJ 4319 PI 36-75 Vdc 3.3 V/15 A 50 W PKJ 4510 PI 36-75 Vdc 5 V/15 A 75 W PKJ 4711 PI 36-75 Vdc 12V/6.25 A 75 W PKJ 4713 PI 36-75 Vdc 1.5 V/20 A 30 W PKJ 4318 PIOAT 36-75 Vdc 1.8 V/20 A 36 W PKJ 4318 PIT 36-75 Vdc 2.5 V/20 A 50 W PKJ 4519 PI 36-75 V dc 3.3 V/20 A 66 W PKJ 4610 PI 36-75 Vdc 5 V/20 A 100 W PKJ 4111 PI 36-75 Vdc 12 V/8.3 A 100 W PKJ 4113 PI 36-75 Vdc 1.5 V/30 A 45 W PKJ 4418 PIOAT 36-75 Vdc 1.8 V/30 A 54 W PKJ 4518 PIT 36-75 Vdc 2.5 V/30 A 75 W PKJ 4719 PI 36-75 V dc 3.3 V/30 A 100 W PKJ 4910 PI 36-75 Vdc 5 V/30 A 150 W PkJ 4111A PI 36-75 Vdc 12 V/12.5 A 150 W PKJ 4113A PI (c) Ericsson Microelectronics, August 2000
