system design. This family can be
powered from either a 3.3V or 5V
supply, and consumes 30mW with a
3.3V supply and 50mW at 5V. The
high speed SPI-compatible CMOS or
LVDS serial interface is ideal for highly
integrated high speed systems.
The LTC2311-16 is available today in
commercial, industrial and automotive
(-40°C to 125°C) temperature grades.
Other devices in the family will be
releasing through 2016. Pricing
begins at $9.95 each in 1,000-piece
quantities. Samples and demo boards
may be requested LTC2311-16, or by
contacting your local Linear Technology
sales office.

Intersil’s 5A and 3A Power
Modules Offer Industry-
Leading Power Density and
Efficiency
Intersil Corporation (NASDAQ:
ISIL), a leading provider of
innovative power management and
precision analog solutions, today
announced two new single-channel
DC/DC step-down power modules
that deliver high power density and
up to 95% efficiency in a compact
4.5mm x 7.5mm x 1.85mm footprint.
The pin-compatible 5A ISL8205M
and 3A ISL8202M provide point-of-
load (POL) conversions for FPGAs,
DSPs and MCUs in a wide range
of home networking and high-end
consumer products, as well as
portable industrial equipment that
use Li-ion batteries. The modules
are complete power supplies that
include a controller, MOSFETs,
inductor and passive components
inside an encapsulated module,
simplifying system design.
With a height of 1.85mm, the
ISL8205M and ISL8202M can be
directly mounted on the backside of
a PCB, freeing up valuable space for
topside mounted components. Both
devices support input voltages from
2.6V to 5.5V and offer adjustable
output voltages as low as 0.6V. The
pin compatibility allows engineers
to start with a 3A power module
and later migrate to the higher 5A
output current, or design a power
tree with multiple POL output rails.
For battery-operated applications,
the ISL8205M and ISL8202M offer
unique efficiency and power saving
features to extend battery life and
support Energy Star® compliant
products. Selectable light load
efficiency, 100% duty cycle modes
and 50µA quiescent current enable
better efficiency and lower power
consumption at light load.
Both power modules leverage
Intersil’s
patented
technology
and advanced packaging to offer
high power density and superior
thermal dissipation performance.
A copper lead-frame structure
allows the modules to operate at
full load over a wide temperature
range with no airflow or heatsinks.
The ISL8205M and ISL8202M also
provide several protection features
that ensure safe operations under
abnormal operating conditions,
further enhancing their robustness
and reliability.
“The ISL8202M and ISL8205M
analog power modules speed time
to market and provide the industry’s
best combination of power density
and performance,” said Mark
Downing, senior vice president of
Infrastructure and Industrial Power
Products at Intersil. “Their size,
light load efficiency and 100% duty
cycle performance gives customers
everything they need to address
their increasingly compact battery-
powered designs.”
