Intersil’s 2A, 3A and 4A, 1MHz Synch Buck Regulators Provide High-Efficiency, Small Form-Factor Power Solutions
ISL8012/13/14 achieve up to 95% Efficiency with Fast Transient Response and Superior Loop Stability and Reduce BOM Costs in Battery-Powered, Computing, Industrial and General Purpose Designs
MILPITAS, CA, June 27, 2008 – Intersil Corporation (NASDAQ Global Select:
ISIL), a world leader in the design and manufacture of high-performance analog
semiconductors, today introduced the
ISL8012,
ISL8013,
and
ISL8014. This family of monolithic synchronous step-down DC/DC regulators
provides a compact, efficient power solution for a wide range of consumer,
computer, industrial and instrumentation applications.
The
ISL8012/13/14
perform high-efficiency DC/DC control and conversion while supporting a
continuous load of 2A, 3A and 4A, respectively. The selectable operation mode
between forced PWM mode and automatic PWM/PFM mode maximizes battery life in
portable and handheld applications. The low quiescent current of 35μA to 40μA in
a light-load/stand-by condition makes this regulator family ideal for battery
powered and other “green power” applications. The supply voltage range of 2.7V
to 5.5V allows the use of single Li+ cell, three NiMH cells or a 3V/5V input.
The
ISL8013 and
ISL8014
are pin-to-pin compatible, while the
ISL8012
comes in a 25% smaller 3mm x 3mm 10-lead DFN package.
In addition to integrating a pair of low ON-resistance switching MOSFETs, the
ISL8012/13/14
can be synchronized to an external clock (up to 4MHz) allowing use of smaller
external components. These devices also feature internal current mode
compensation to minimize the number of external components while enabling a fast
transient response and high duty cycle/low drop-out operation. Inherent output
voltage monitoring and power sequencing can be realized using features such as
Power-On-Reset (POR), PGOOD (Power OK) and Enable (EN) to provide output voltage
monitoring and power sequencing capabilities without the need of additional
discrete ICs.
The
ISL8012/13/14
also feature less than 1μA logic-controlled shutdown current, peak current
limiting and hiccup mode short circuit protection for reliable operation under
adverse conditions. External synchronization up to 4 MHz (for
ISL8013
and
ISL8014) reduces electromagnetic emissions between multiple rails on the
system board.
The
ISL8012/13/14
family is an ideal power solution for a wide range of applications such as
digital cameras, media players, portable medical instruments, broad range of
computing applications including servers, storage drives, KVM modules,
industrial programmable logic controllers, data acquisition systems, etc.
Pricing and Availability
The
ISL8012 is available now in a 10 Ld. 3x3 DFN package and is priced at $1.85
in 1,000-unit quantities. The
ISL8013
and
ISL8014 are available now in a 16 Ld. 4x4 QFN package and are priced at
$2.71 and $3.71, respectively, in 1,000-unit quantities. More information on the
