The NX4108-12CZ1TR is a switching regulator from the Power Management Integrated Circuit (PMIC) family. It belongs to the Voltage Regulators and the DC DC Switching Regulators category. It is a low profile (1mm height), synchonouse buck regulator. It features ultra-low quiescent current of 1.1uA and can be used for applications such as Bluetooth Low Energy (BLE), Wi-Fi, Battery Management Systems (BMS), Mobile and IoT with Noise Level Control.

It has a switching frequency of up to 1.5MHz and uses an Internal N-Channel MOSFET, making it ideal for low-power applications that require high efficiency. It has an adjustable output voltage with a typical voltage range of 0.9V to 4.5V, and it can support an operating current up to 4A, making it suitable for low current and high current applications.

The NX4108-12CZ1TR has an integrated advanced Current Mode Control (CMC) architecture which can achieve a fast transient response with a typical output voltage accuracy of ±3.3%. It has an auto-shutdown feature which can be enabled or disabled by an external control pin, allowing for a significant power saving. It also has a Temperature Compensation circuit which can keep the output voltage stable under temperature changes, eliminating the need for external compensation for temperature effects.

The NX4108-12CZ1TR has a wide range of protection features to ensure safe operation. These include an Over Temperature Protection (OTP) which will shut off the switch when the die temperature reaches 140℃, a Current Limit Protection (CLP) which will limit the output current when it exceeds the upper limit, and an Over Voltage Protection (OVP) which will limit the output voltage if it exceeds the upper limit.

The NX4108-12CZ1TR has an internal soft start during startup, which can be disabled through an external control pin. Soft start is used to ensure a smooth and quiet startup of the switching regulator, preventing the start-up current spikes which can damage the components connected to the regulator.

The NX4108-12CZ1TR has an adjustable operating frequency, allowing for the optimization of the efficiency for different output voltage levels. The higher the operating frequency, the higher the efficiency, but the higher the output voltage ripple. There is also an integrated Spread Spectrum (SS) architecture which can effectively reduce EMI by adjusting the operating frequency.

In summary, the NX4108-12CZ1TR from PMIC – Voltage Regulators – DC DC Switching Regulators is a highly efficient and reliable switching regulator for low-power applications. It features a wide range of protection features along with an adjustable output voltage, high operating current and wide operating frequency range. It has integrated soft start and spread spectrum capabilities, making it ideal for low-power applications.
