Silicon Mitus SM4805 integrates high efficiency switching regulators and low noise op-amps, which effectively support UHD TV LCD Panels

SEOUL-PANGYO, South Korea-- 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 panels.

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.
