Datasheet
The TPS65175RSHR is a power management IC designed for use in small display applications, such as wearables, handheld devices, and small LCD panels. The device includes an integrated boost converter, a negative charge pump, and a positive LDO regulator, which provide the voltage needed to drive the display.
The boost converter provides a regulated output voltage of up to 18V and is used to power the backlight of the display. The negative charge pump produces a negative voltage that is used to drive the LCD panel. The positive LDO voltage regulator provides the voltage regulator for the digital circuit of the display.
The TPS65175RSHR also includes built-in protection features such as overcurrent protection, overtemperature protection, and undervoltage locking. These features help ensure the reliability and security of the device.
The device comes in a small 16-pin VQFN package with a size of only 3mm x 3mm. It has a wide input voltage range of 2.5V to 5.5V, making it suitable for a wide range of battery types. The device’s boost converter has a maximum output current of 100mA, the charge pump has a maximum output current of 50mA, and the LDO regulator has a maximum output current of 50mA.
The TPS65175RSHR is a highly integrated and efficient solution for small display applications. Its compact size, wide input voltage range, and built-in protection make it ideal for wearables, handheld devices, and other small LCD applications.
