SM4053C IC Circuit Diagram Datasheet Pinout and Voltage Details

 SM4053C IC contains one buck converter for VGL output and three boost converters for VDD, HVDD, and VGH output. This multi-function IC has several DC-to-DC converters, gamma, logic level shifters, and VCOM sections. Moreover, SM4053C IC provides overload-protected VGH ODD and EVEN output with a flip-flop technique.

Application- Power management of LCD TV and LCD Monitor display panel
Package- QFN Quad flat no-lead package
Number of terminals - 14x4 = 56
Operating Voltage VIN -  DC 9.4 Volts to 14 Volts
Logic Voltage (Vlogic) - 3.3 Volts

Protection - Excellent protection against over-voltage, short circuit, over-current, and over-temperature events is provided by the SM4053 IC, which protects the LCD panel.

The output voltages of SM4053 IC - VDD 15 Volts, HVDD - 7.5 Volts, VGL- -5 Volts, VGH- 27 Volts.
CLK1, CLK2, CLK3, CLK4, CLK5, and CLK6 are usually 7 volts.
Gamma output voltages are different voltages for different displays.
The flip-flop voltages of VGH ODD and EVEN are sequentially -5V and +27V.
