The NCP81111MN is a multi-voltage device optimized for battery-powered applications. It is commonly used in mobile phones, tablets, and other battery-powered devices. The device integrates both buck (high input voltage, low output voltage) and boost (low input voltage, high output voltage) controls and provides the necessary assistance for power management in battery-powered applications, helping to extend the battery’s life. The device accepts an input voltage between 2.5 V to 5.5 V and can provide an output voltage as low as 0.8 V or as high as 5.5 V.

The NCP81111MN has numerous features for popular battery-powered applications. It features a power-saving sleep mode, which enables the device to switch over to a low-power standby mode when no load current is detected, thereby helping to improve the device’s overall power efficiency. A guarantee of 1% tolerance on the voltage output, up to a maximum output of 1A, improves accuracy, saving design time and money. The device also has a power-on reset (POR) feature, which helps to prevent current peaks during start-up and a power-off reset (POF) feature, which helps to prevent current peaks during VOFF conditions. Other features, such as N-channel MOSFET gate control, programmable soft-start function, adjustable switching frequency, overcurrent protection and thermal shutdown protection, help to improve system reliability.

The NCP81111MN offers a number of different options for powering the device. It can be powered using a single input supply or multiple input supplies, allowing designers to choose the best solution for their application. The device also supports data capture, monitoring and control functions through an I2C or SPI interface, as well as digital diagnostics, such as undervoltage and overcurrent protection.

The NCP81111MN offers many features and integrated functions for a wide range of applications. It is used in portable electronics, including mobile phones, tablets, digital cameras, wearables, GPS and Bluetooth devices, gaming devices and LED lighting. It can be used in industrial, automotive and general-purpose applications, as well as in higher-voltage applications, such as programmable power supplies and telecom power systems.

The working principle of the NCP81111MN is based on a DC-DC buck/boost converter design. The device uses a high-frequency converter that switches rapidly between a low-side and a high-side switch to control the output voltage. When the input voltage is higher than the output voltage, the device works as a buck converter, which allows the voltage to drop by changing the duty cycle of a high frequency switch. When the input voltage is lower than the output voltage, the device works as a boost converter, which allows the voltage to be increased by changing the duty cycle of a high frequency switch.

The NCP81111MN is an advanced multi-voltage controller that provides power management features for improved efficiency, performance and safety in a wide range of battery-powered applications. Its ability to support single or multiple supplies, digital diagnostics, power-saving sleep mode, programmable soft-start and N-channel MOSFET gate control make it an ideal choice for mobile devices such as phones and tablets, as well as industrial, automotive and general-purpose applications.
