Silicon Mitus SM4805 integrates high efficiency switching regulators
and low noise op-amps, which effectively support UHD TV LCD Panels
SEOUL-PANGYO, South Korea–(BUSINESS WIRE)–lt;a href=”https://twitter.com/hashtag/ICs?src=hash” target=”_blank”gt;#ICslt;/agt;–Silicon
Mitus, Inc. (Silicon Mitus), an advanced specialist in Power
Management Integrated Circuit (PMIC) and Audio Semiconductor Solution,
launched the SM4805, a highly integrated multi-output PMIC which
successfully meets UHD TV LCD panel application requirements. The device
has an input voltage range of 10.2 V to 14.7 V, and it is the first
single chip available on the market capable of powering large UHD TV LCD
The AVDD boost controller drives the external switches to deliver high
power at voltages required by the application. Three buck converters
regulate output voltages in the range of 0.8 V to 3.5 V with an output
current of up to 2.5 A, and the output voltages and power up sequence
are programmable through the digital interface. The SM4805 also includes
4-channel gamma buffers and two VCOM op-amps that feature low noise
output. Despite accomplishing a high degree of integration, the device
runs at a lower temperature due to highly efficient DC-DC converters
based on specialized IPs.
“With heightened levels of power consumption and power rails in UHD TV
LCD panels, LCD panel PMICs require higher output power and integration
with higher efficiency at lower IC temperatures. We are proud to offer
the SM4805 that makes this possible as part of the Silicon Mitus TV LCD
PMIC exhaustive portfolio,” said Henry Jung, Head of Display Marketing.

The device is offered in a 56 QFN package, and samples are available.
