BMR469 series

2×25A and 2×40A Non-Isolated Digital DC/DC PoL Regulator

The BMR469 series is a dual output digital non-isolated DC/DC PoL converter housed in a 25.4 x 14.5 x 5.8mm (2x25A) or 25.4×12.7×11.6mm (2×40A) package. They offer a Vout range between 0.6-5.0V and a wide Vin range from 7.5-14V typically used in Intermediate Bus Architectures found in industrial, telecom and datacom applications.

These converters can deliver up to 2×40A (or 1×80A in a single output configuration) and have a high efficiency up to 92.6% typical at 12Vin / 5Vout / 50% load.

The BMR469 series has MTBF of up to 18.5 million hours.

Standard features for this model include configuration, control and monitoring via PMBus®, user configurable feedback loop compensation, frequency synchronization, phase spreading/interleaving, voltage tracking and voltage margining.

The BMR469 is supported by our own Flex Power Designer tool.

Evaluation of the 2 x 40A BMR4690000 is possible using the ROA170111 Eval Board, while the 2 x 25A BMR4696001 can be evaluated using the ROA170111/1 board
