EM2260P01QI 60A PowerSoC
Step-Down DC-DC Switching Converter with Integrated Inductor, Featuring
Digital Control with PMBus
TM
V1.3 Compliant Interface
Description
The EM2260 is a fully integrated 60A PowerSoC
synchronous dual-phase buck converter. It features
an advanced digital controller, gate drivers,
synchronous MOSFETs, and high-performance
inductors. Only input and output filter capacitors
and a few small signal components are required for
a complete solution. A PMBus version 1.3 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 EM2260 can be configured and controlled in
any application by two methods, either in pin-strap
mode using onboard resistors, or using the PMBUS
interface. The customer can also configure the
device during engineering evaluation using the
PMBUS interface, which offers a high degree of
flexibility and programmability, and then use the pin
strap mode when devices are deployed in
production. Advanced digital control techniques
ensure
stability
and
excellent
dynamic
performance, and eliminate the need for external
compensation components. The Intel Enpirion
Digital Power Configurator provides a user-friendly
and easy-to-use interface for communicating with
and configuring the device.
The EM2260 features high conversion efficiency
and superior thermal performance to minimize
thermal de-rating limitations, which is key to
product reliability and longevity.
