BMR473 Digital Point-of-Load (PoL) Regulator
The Flex Power Modules BMR473 is a 40 A non-isolated, digital PoL regulator in compact single inline package (SIP) design
The Flex Power Modules BMR473 is a digital PoL converter packaged in a space-saving SIP 2.3 cm2 or horizontal mount format. The product is single phase and rated at 40 A continuous, and up to four can be paralleled for up to 160 A. Multiple BMR473 can be synchronized for low EMI. Its phase spreading/interleaving capability dramatically reduces input capacitance requirements and efficiency losses. Excellent thermal performance, a custom inductor design, and efficiency levels up to 96.1% allow full load operation to +95°C in free air (12 VIN/1.8 VOUT) and up to +100°C ambient with suitable airflow and derating. Input is rated from 6 V to 15 V, and the output is programmable from 0.6 V to 5 V.
PMBus® interface is provided to enable monitoring of Vin, Vout, Iout, and module temperature. PMBus configuration possibilities include input overvoltage and undervoltage protection thresholds and output overcurrent limit. A programmable overtemperature protection limit is featured along with settable switching frequency and output rise/fall and on/off delay times and settable switching frequency. A power good (PG) signal is also provided. Output voltage can be set via the PMBus or with external resistors. Back-channel communication between paralleled modules is implemented so that a single address can represent the modules, simplifying system software design.
The SIP version of the BMR473 is 26.3 mm x 8.8 mm x 15.6 mm, occupying less than 2.3 cm2 board area.
