Industry's Smallest Form Factor 1.6MHz Synchronous Buck Regulator Provides 95% Efficiency
Tiny ISL8009A Regulator Supports Continuous 1.5A Load Ideal for Extending Battery Life in a Wide Range of Computer, Consumer, Peripheral and Instrumentation Designs
MILPITAS, CA, April 10, 2008 – Intersil Corporation (NASDAQ Global Select:
ISIL), a world leader in the design and manufacture of high-performance analog
semiconductors, today introduced the
ISL8009A,
an ultra-small, high-efficiency synchronous buck regulator that saves space and
offers improved efficiency for a broad range of applications.
The
ISL8009A comes in an 8-lead, 2mm x 3mm DFN package and performs DC/DC
control and conversion while supporting a continuous load of 1.5A. The device’s
current mode control architecture delivers very low duty cycle operation at high
frequency with fast transient response and excellent loop stability. It can
operate in forced PWM mode or automatic PFM/PWM mode with quiescent current as
low as 17 microamps.
The
ISL8009A’s highly efficient power conversion under light load conditions
extends battery life in portable and handheld applications. A pair of low
ON-resistance P-Channel and N-Channel switching MOSFETs is integrated into the
IC resulting in a very small regulator footprint. In addition, the internal
compensation requires less external components. These features provide a
space-saving solution for digital cameras, media players, portable medical
instruments, servers, storage drives, KVM modules, industrial programmable logic
controllers and other applications.
A 2-millisecond Power-on-reset (POR) and enable (EN) outputs provide internal
voltage monitoring and sequencing. The timer output can be reset through the
reset system input (RSI) pin. For additional safety, the
ISL8009A
discharges the output capacitor through a 100 ohm resistor when the application
is shut down.
Other features include internal digital soft-start, enable for power sequence,
overcurrent protection, and thermal shutdown.
Pricing and Availability
The
ISL8009A is available now in 8-lead 2mm x 3mm DFN packages, just 1 mm in
height. Pricing starts at $1.52 each in 1,000-piece quantities.
