NCV8161BMX250TBG Application Field and Working Principles

NCV8161BMX250TBG, categorized as PMIC (Power Management IC) – Voltage Regulators – Linear, is a low power, low dropout linear regulator. It is used for a wide range of applications such as computing, networking, industrial, and consumer products. This device is used to convert an input voltage to a stable and adjustable output voltage.NCV8161BMX250TBG operates at a wide input voltage range of 2.2V to 14V, with a maximum output voltage drop of 0.15V. It is efficient with quiescent current consumption as low as 45μA. The high power factor of 99% is achieved through the use of a feedback loop that adjusts with the output voltage variation. This ensures that the output voltage remains constant even with the input voltage variation. The device also features automatic fold-back current limiting and thermal shutdown providing over-temperature protection.The design of NCV8161BMX250TBG is based on a single stage architecture. It consists of a high-performance, low-power N-channel MOSFET as a power switch. The MOSFET is referenced to a low-noise reference voltage of 0.8 V which is generated by a bandgap circuit. The MOSFET is then biased by the output voltage and current sense circuit to the reference voltage.The operation of NCV8161BMX250TBG is based on a linear mode of regulation. It works by monitoring the output voltage and adjusting the duty cycle of the power switch (MOSFET) in relation to the input voltage. The output voltage is maintained at the selected level by increasing or decreasing the duty cycle of the power switch. This allows the stability of the device to be maintained even in the presence of input voltage and load variations.The main features of the NCV8161BMX250TBG include a low-dropout performance, a low quiescent current and an adjustable output voltage. With a maximum operating current of 250mA, NCV8161BMX250TBG can be used in a variety of applications requiring low-power regulation. It is also designed to be used in environments where the minimum output voltage is 2.8V, making it suitable for a variety of LED applications. In summary, the NCV8161BMX250TBG is a low power, low dropout linear regulator that is ideal for a variety of applications including computing, networking, industrial, and consumer products. It offers good performance, low-dropout, low quiescent current, and an adjustable output voltage. Its operation is based on linear mode of regulation which ensures the stability of the device in the presence of input voltage and load variations.
