The new FAN5336 high-frequency integrated boost converter from
Fairchild Semiconductor (NYSE:FCS) allows designers to achieve a
remarkable 87 percent system efficiency, low EMI and board space
savings in a wide range of small LCD bias supply and white LED
backlight designs. This 1.5MHz switching boost converter features a
wide output-voltage range (9-33V) and integrates a switching NFET
into an ultra-thin-profile, molded leadless package (UMLP) that
measures only 3 x 3 x 0.6mm. Smaller than SOT-packaged devices
typically used in these applications, the FAN5336 offers more
functionality including higher peak current (1.5A) than similar
1.0A devices, as well as excellent line and load regulation (0.2
percent) and high switching frequency (1.5MHz). As a result, the
FAN5336 helps to minimize noise, heat generation and emissions in
cell and smart phones, MP3 players, medical devices and many other
portable applications. Additionally, the converter�s high frequency
allows the use of smaller components, helping designers maximize
board space while easing design complexity. �Fairchild�s FAN5336 is
an excellent choice as an all-purpose boost converter for a variety
of display applications,� said Bruno Kranzen, Ultra-Portable
Product Line director for Fairchild. �Designers will find this
device especially beneficial in today�s small LCD bias supplies and
white LED backlight supply applications that require an input range
of 2.7V to 5.5V. In these designs, FAN5336 delivers 87 percent
efficiency by providing at least 100mA load current into an output
rail set between 9V to 21V, and 50mA current into an output as high
as 33V.� Kranzen continued: �Fairchild developed the FAN5336 to
offer designers another option in our growing portfolio of
integrated boost converter solutions that cover a broad range of
applications. Other products include the FAN5331 and FAN5332 with
20V and 30V output voltages, respectively.� In addition to
efficiency advantages, the FAN5336 offers features for system
reliability including cycle-by-cycle current limit, 1.5A peak
current support and soft-start capability. The FAN5336 is available
in 6-terminal UMLP and MLP packages. These lead (Pb)-free packages
meet or exceed the requirements of the joint IPC/JEDEC standard
J-STD-020C and are compliant with European Union regulations now in
effect. Price (each, 1000 pcs): US$ 0.91 (3 x 3 x 0.6mm, UMLP) US$
0.86 (3 x 3 x 0.8mm, MLP) Availability: Now Delivery: 6 to 8 weeks
