EM2130x0xQI 30A PowerSoC
Step-Down DC-DC Switching Converter with Integrated Inductor, Featuring
Digital Control with PMBus
TM
v1.2 Compliant Interface
Description
The EM2130 is a fully integrated 30A PowerSoC
synchronous buck converter. It features an
advanced digital controller, gate drivers,
synchronous MOSFET switches, and a high-
performance inductor. Only input and output filter
capacitors and a few small signal components are
required for a complete solution. A PMBus version
1.2 compliant interface provides setup, control, and
telemetry.
Differential remote sensing and ±0.5% set-point
accuracy provides precise regulation over line, load
and temperature variation. Very low ripple further
reduces accuracy uncertainty to provide best in
class static regulation for today’s FPGAs, ASICs,
processors, and DDR memory devices.
The EM2130 may be used in standalone mode or
utilizing the PMBus interface for a high degree of
flexibility and programmability. Advanced digital
control techniques ensure stability and excellent
dynamic performance and eliminate the need for
external compensation components. The PC-based
Intel Enpirion Digital Power Configurator provides a
user-friendly and easy-to-use interface to the
device for communication and configuration.
The EM2130 features high conversion efficiency
and superior thermal performance to minimize
thermal de-rating limitations, which is key to
product reliability and longevity.
