RAA210925
Pin-Configurable Dual 25A DC/DC Power Module with PMBus Interface
FN9352
Rev.1.00
May 31, 2019
The
RAA210925
is a pin-strap configurable dual 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 RAA210925
simplifies configuration and control of Renesas
digital
power technology
while offering an upgrade to full
PMBus configuration through the pin-compatible
ISL8274M.
Operating across an input voltage range of 4.5V to 14V, the
RAA210925 offers adjustable output voltages down to 0.6V
and achieves up to 95.5% conversion efficiencies. A unique
ChargeMode™ control architecture provides a single clock
cycle response to an output load step and can support
switching frequencies up to 1067kHz. The power module
integrates all power and most passive components and
requires only a few external components to operate. The
RAA210925 comes with a preprogrammed configuration
for operating in Pin-strap mode. Output voltage, switching
frequency, input UVLO, soft-start/stop delay and ramp
times, tracking function, and the device SMBus address can
be programmed with external pin-strap resistors. A standard
PMBus interface addresses fault management, as well as
real-time full telemetry and point-of-load monitoring. The
RAA210925 is supported by PowerNavigator™ software,
a Graphical User Interface (GUI), that can configure
modules for desired solutions.
The RAA210925 is available in a low profile, compact
18mmx23mmx7.5mm fully encapsulated, thermally
enhanced HDA package.
