Intersil R3 Technology™ Provides World's Best Transient Response and Switching Efficiency for Notebook Peripheral Power
— The ISL6228 Dual-Output Buck Controller Offers Fast Transient Response Through a Hybrid Fixed/Variable frequency PWM and Wider Voltage Range Options (3.3V to 25V Input; +0.6V to +5V Output) for Flexibility
MILPITAS, CA, September 20, 2007 – Intersil Corporation (NASDAQ Global
Select: ISIL), a world leader in the design and manufacture of high-performance
analog semiconductors, today announced the release of the
ISL6228
high-performance dual-output buck controller for notebook peripheral computing
applications. Through Intersil’s patented R3 Technology™
this controller provides unmatched transient response, switching efficiency and
design flexibility.
The
ISL6228 is capable of operating over the industry’s widest input voltage
range (3.3V to 25V) and has a highly flexible output voltage range from +0.6 to
+5.0V. These broad voltage ranges, combined with dual independent switchers,
make this controller the ideal choice for notebook peripheral applications, as
well as a host of general purpose communications, storage, security and
industrial automation applications.
Intersil’s R3 (Robust Ripple Regulator) Technology™
provides the dynamic response to input voltage and output load transients
required by today’s faster, more powerful notebook processors. The R3
Technology represents a hybrid of fixed-frequency PWM control and
variable-frequency hysteretic control to produce the industry’s fastest
transient response.
The
ISL6228 features a self-adjusting PWM that sets to the most efficient
switching frequency between 200kHz and 600kHz based on the requirement of the
load transient. This programmable PWM delivers superior switching efficiency and
enhanced design flexibility. Efficiency is further maximized by automatic
switching between continuous-conduction-mode (CCM) and diode-emulation-mode
(DEM) during light loads.
The
ISL6228 features enhanced fault protection against undervoltage, overvoltage,
overcurrent and over-temperature. The device also has a DCR inductor and fault
ID, all of which are monitored through a multi-function PGOOD pin.
With an integrated MOSFET driver and bootstrap diode, the
ISL6228
further eliminates the need for external components, lowering BOM and saving
board space for designs.
Pricing and Availability
The
ISL6228 is available now in a 28-lead TQFN package and is priced at $2.20
per unit in 1,000-unit quantities for bulk packaging and $2.25 per unit for
tape-and-reel packaging. More information on the
