New Micrel Family of Integrated FET DC-to-DC Buck Converters Provides Highest Performance at Optimized Solution Costs for 12V Input Rails
SAN JOSE, CA, Feb 27, 2013 (MARKETWIRE via COMTEX) --
Micrel, Inc. (NASDAQ: MCRL), an industry leader in high-performance
Linear and Power solutions, LAN and timing and communications
solutions, today rolled out its latest-generation SuperSwitcher
II(TM) family of integrated MOSFET buck regulators optimized for the
12V rails, with 6A/9A/12A output supply current. The new MIC2405x
family is comprised of six common-footprint, DC-to-DC buck regulators
that leverage Micrel's proprietary HyperSpeed Control(TM) and
HyperLight Load(R) architectures. The devices provide flexible,
cost-effective solutions for distributed power systems,
communications networking and infrastructure, and industrial
applications. The MIC24051/2 (6A), MIC24053/4 (9A), MIC24055/6 (12A)
are currently available in volume quantities, with 1,000 quantity
pricing starting at $0.91, $1.04 and $1.22 respectively. Samples can
be ordered at:

"Power supply designers today experience growing challenges in
identifying flexible cost-optimized solutions for their
high-power-density, small-real-estate needs," noted Brian Hedayati,
vice president of marketing for high-performance linear and power
solutions at Micrel. "Micrel's MIC2405x SuperSwitcher family utilizes
Micrel's proprietary architectures to enable light-load efficiency
and high-V(IN) to low-V(OUT) conversions over a wide range of output
currents, at an attractive solution cost. This results in exceptional
value for systems that require minimum board space and maximum
efficiency in order to reduce the power supply heat representing more
than 25 percent of the cost of cooling these systems."
The MIC2405x family of devices (MIC24051/2/3/4/5/6) operates with a
single-input supply voltage range from 4.5V to 19V, and delivers
output currents of 6A, 9A and 12A respectively, all in small
footprint MLF-28, 5mmx 6mm packages. The common footprint shared by
all devices in this family enables current scalability which in turn
provides design flexibility for the power supply designer. This
family of regulators has been tailored to be Any Capacitor(TM)
stable, independent of the output capacitance Equivalent Series
Resistance (ESR), thus solving the perpetual problem of stability
that power designers face when dealing with distributed output
capacitance. Moreover, these buck regulators provide more than 95
percent peak efficiency and operate at 600kHz switching frequency
with +/-1 percent of output voltage accuracy (with output adjustable
down to 0.8V).
The MIC2405x regulators offer a full suite of protection features to
ensure protection of the IC during fault conditions. These include
under-voltage lockout to ensure proper operation under power-sag
conditions, thermal shutdown, internal soft start to reduce the
inrush current, and foldback current-limit and "hiccup" mode
short-circuit protection. The devices also feature a power good (PG)
output to allow simple sequencing. The MIC2405x regulators are
available in a thermally enhanced 28-Lead 5mm x 6mm MLF(R) package.
