Expanding its point of load (POL) range of dc-dc regulators, Ericsson Power Modules has introduced two small POLA devices. The PMD series regulators offer a solution for low current applications. The device incorporates highly integrated functionalities in a single chip control IC less than 2.4 cm2.
The PMD4000 is a 3-A POL regulator that provides an output range of 0.9 V to 3.6 V at 10.8 W for 3.0-Vin to 5.5-Vin applications, and the PMD5000 is rated at 2.25 A, providing 0.9 V to 5.5 V, 12 W for 4.5-Vin to 14-Vin applications. An advanced feature of the PMD is AutoTrack, which tracks an external voltage ramp to achieve simultaneous start up/shut down.
Ericsson’s PMD series dc-dc regulators are designed to POLA standards to provide maximum flexibility for PC board power designs. POLA ensures full compatibility between all participating member products.
