FAN2106 Saves Board Space and Delivers up to 6 A Output Current
Fairchild introduced the FAN2106, the
first product in a new family of TinyBuck™
DC/DC buck regulators that integrate an
advanced analog IC, MOSFETs and a
bootstrap diode into an ultra-compact
moulded leadless package (MLP).
Measuring only 5 x 6 mm, this highly integrated
synchronous buck regulator consumes
approximately 50 % less board space
than discrete solutions and facilitates
greater design flexibility.
Input Range of 3 to 24 V
Furthermore, the FAN2106 achieves up to
95 % power efficiency by converting 3 to
24 V input voltages to output voltages as
low as 0.8 V while delivering up to 6 A output
current. This compact, easy-to-use regulator
is ideal for use in a wide range of POL
(point-of-load) applications, including settop
boxes, cable modems, in-cabin GPSs,
portable medical equipment, LED lighting,
industrial instrumentation as well as ultramobile
PCs, notebooks and blade servers.
Programmable Switching Frequency, 600 kHz max.
For loads between 1 A and 6 A, the operating
efficiency of the FAN2106 generally ranges
between 85 and 95 %, and lower switching
frequencies tend to increase the operating
efficiency of the device. In certain cases (for
example, when the input voltage is 8 V, the
output voltage is set to 3.3 V, and the
switching frequency is 300 kHz) efficiency
can rise slightly above 95 %. The maximum
supported switching frequency is 600 kHz.
Fairchild´s TinyBuck™ all-in-one modules
combine state-of-the-art device packaging
technology with superior integrated features.
These regulator devices enable engineers
to meet their primary design challenges:
saving board space, simplifying
designs and increasing power efficiency.
