AP2161DMPG-13 Application Field and Working Principle

The AP2161DMPG-13 is a PMIC (Power Management Interface Chip) with a power distribution switch, load driver, and low-dropout linear voltage regulators. The device keeps display panels and LED lighting systems connected and operating when power is limited. It is mainly used in portable electronics such as smartphones, tablets, and notebooks.

Features

The AP2161DMPG-13 PMIC provides the following features:

• Wide VIN range 2.7V to 5.5V
• Integrated 2-channel power distribution switch
• Low Ron, adjustable 0Ω/1.8Ω/2.7Ω
• Integrated one load driver with adjustable OVP, up to 17V
• Integrated one low-dropout linear voltage regulators
• Low quiescent current in sleep mode
• Integrated pump switch and level shifter
• Over-temperature protection, over-current protection and short-circuit protection

Working Principle

The AP2161DMPG-13 PMIC is designed to manage and distribute power in a variety of applications. It provides power for LEDs and LCD displays, allowing them to remain operated in limited power situations.This PMIC contains two key components:

• Power Distribution Switch
• Load Driver

Power Distribution Switch

The power distribution switch is composed of two independent high-side and low-side switches. The switch uses the voltage input (VIN) to control the power output, allowing the user to adjust the input current and the output voltage. The low-side switch is connected to the common ground, while the high-side switch is used to control the voltage output. The two switches can be turned on and off independently, allowing for multiple power options for different applications.

Load Driver

The load driver is a high-power, high-efficiency, adjustable voltage regulator that is designed to drive loads up to 17V. The load driver is connected to the output of the power distribution switch and is used to regulate the output current, allowing for a stable output voltage. The load driver also provides over-temperature protection, over-current protection, and short-circuit protection.

Applications

The AP2161DMPG-13 PMIC is used in portable electronic devices such as smartphones, tablets, and notebooks. It is also used in LED lighting systems and automotive infotainment systems. The device is ideal for applications where power is limited and power conservation is important.
