Expanding its point of load (POL) range of DC/DC regulators, Ericsson Power Modules has introduced two POLA devices that it claims are among the smallest switching POL regulators available, and provide high efficiency and a host of features for "real needs" applications at low cost.

The PMD series regulators offer a "quick" solution for low current applications, the company said. Using highly integrated functionalities in a single chip control IC less than 2.4cm?, the PMD offers flexibility to designers whenas is often the casea board's complexity limits the available room for power circuitry. The small size also offers the possibility to incorporate other value-adding components.

The PMD4000 is a 3A POL regulator providing an output range of 0.9-3.6V at 10.8W for 3-5.5Vin applications, and the PMD5000 is rated at 2.25A, providing 0.9-5.5V, 12W for 4.5-14Vin applications. An advanced feature of the PMD is AutoTrack that tracks an external voltage ramp to achieve simultaneous start up/shut down.

The versatile modules are available in either surface mount or through-hole formats. Similarly, the regulators' flexible output voltages combined with wide input voltage ranges provided by just two part numbers offers unlimited possibilities while reducing inventory. As a POLA product, buyers can be sure of secure sourcing from at least three other vendors who will be producing interoperable products.

The low current sector for POL is often challenged by discrete solutions that require resources to design and maintain such a solutionwith all the associated costs. Additionally, due to its highly integrated functionalities, PMD requires less board space as a discrete solution. This, combined with the limitation to two part numbers covering all possible combinations of input voltages and output voltages make the product cost efficient throughout the whole chain from board concept to final application, the company said.

Ericsson's PMD series DC/DC regulators are designed to POLA standards to provide maximum flexibility for board power designs. POLA ensures full compatibility between all participating member products.
