Ericsson Power Modules has introduced an additional member in its family of 3E second-generation digital point-of-load (POL) voltage regulators with a new vertical-mount variant of the recently announced 40A-output BMR464 series.

The new BMR464-SIP (BMR4642002) meets demands to save valuable board space for the core components as it enables vertical mounting – also known as single in-line packaging (SIP), which is often used for devices such as memory chips, voltage regulators and other control boards. This approach delivers a device footprint of less than 0.39in2, making the new device ideal for space-critical applications.

The new regulator can also be configured and monitored via the standard PMbus communication protocol and the company’s graphical user interface, making this the first PMBus-compliant 40A point-of-load SIP device available on the market.

The primary end-use applications are network routers, data storage and AdvancedTCA boards, but the low height of the BMR4642002 also makes it suitable for many other applications when space is at a premium. The device’s measurements of 33.00 x 7.6 x 18.1mm make the product suitable for those high-density boards that require a small footprint and height below 20mm, guaranteeing a safe and comfortable fit when assembled in 1-inch rack systems.

In addition to the small footprint of 2.5cm2, key features of the 40A- and 132W-output regulator include a market-leading power density of almost 53W/cm2. The regulator accepts input voltages from 4.5V to 14V and has an output voltage range of 0.6V to 3.3V with typical efficiency of 97.2% at 5Vin, 3.3Vout and 50% load.
