Pin-Configurable 25A DC/DC Power Module with PMBus Interface

The RAA210825 is a pin-strap configurable 25A
step-down PMBus-compliant DC/DC power supply
module that integrates a digital PWM controller,
synchronous MOSFETs, power inductor, and passive
components. Only input and output capacitors are needed
to finish the design. Because of its thermally-enhanced
HDA packaging technology, the module can deliver up to
25A of continuous output current without the need for
airflow or additional heat sinking. The RAA210825
simplifies configuration and control of Renesas digital
power technology while offering an upgrade path to full
PMBus configuration through the pin-compatible
ISL8277M.
The RAA210825 uses ChargeMode™ control
architecture, which responds to a transient load within a
single switching cycle. The RAA210825 comes with a
preprogrammed configuration for operating in a pin-strap
mode. Output voltage, switching frequency, input
UVLO, soft-start/stop delay and ramp times, and the
device SMBus address can be programmed with external
pin-strap resistors. A standard PMBus interface
addresses fault management, in addition to real-time full
telemetry and point-of-load monitoring.
The RAA210825 is available in a 41 Ld compact
17mmx19mm HDA module with very low profile height
of 3.6mm, suitable for automated assembly by standard
surface mount equipment. The RAA210825 is RoHS
compliant by exemption.
