Ericsson has added a vertical-mount version to its BMR464 digital PoL voltage regulators. Functionality on board level designs is growing as single core processors migrate to multi-core porcessors and advanced FPGAs. There is also the increasing trend for system upgrades with additional features on boards. This limits space available for peripheral devices, such as the voltage regulator. The BMR464-SIP (single in-line packaging), the BMR4642002 enables vertical mounting, which is often used for devices such as memory chips, voltage regulators and other control boards. As a result, device footprint is less than 25mm². The regulator can be configured and monitored via the standard PMbus communication protocol and the company's GUI. According to the company, this makes it the first PMBus-compliant, 40A PoL SIP device available. Primary end use applications are network routers, data storage and AdvancedTCA boards. The device measures 33x7.6x18.1mm. The 40A and 132W output regulator has a power density of almost 53W/cm². The regulator accepts input voltages from 4.5 to 14V and has an output voltage range of 0.6 to 3.3V with typical efficiency of 97.2% at 5Vin, 3.3Vout and 50% load.
