Although the VPM2SM’s exact PMIC family is not specified, the company’s focus on OLED display power and portable electronics strongly suggests that the VPM2SM is intended for similar applications.
While the manufacturer's datasheet will have the definitive answer, its documented applications in televisions indicate it plays a critical role in generating or distributing power and signals to the LCD panel. It is likely a specialized power management IC.
Place a low-ESR ceramic bypass capacitor as close to this pin as possible. GND System Ground Reference vpm2sm datasheet
: Generates a high positive bias voltage (+20V to +30V) to switch on the microscopic TFT transistors across rows during screen refreshes.
— For everyone who Googled a part number and found nothing, but built something anyway. Although the VPM2SM’s exact PMIC family is not
The VPM2SM datasheet provides a detailed list of technical specifications, including:
The datasheet provides information on the evaluation board layout and schematic, enabling designers to easily evaluate and integrate the VPM2SM into their systems. Place a low-ESR ceramic bypass capacitor as close
. It is primarily used as an LCD display chip in high-end smartphones, such as the OnePlus 8 series
