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
