The MP2161GJ-ZX is a switching regulator from the product family of DC-DC voltage regulators from the PMIC (Power Management IC) product line, featuring a fully integrated synchronous buck converter with step-down input voltage voltage ranging from 4.4V to 14V. It offers an adjustable output voltage range between 0.8V to 5.5V and switch current up to 6.0A. It is designed for small form factor, low power applications and features high efficiency, excellent load and line transients, and lower EMI.

The MP2161GJ-ZX switching regulator controls two external N-channel MOSFETs to convert a higher input voltage to a lower regulated output voltage. The regulator consists of two independent buck channels with separate inputs. When the input voltage is applied to the input of the regulator, it starts switching the N-channel MOSFETs at a fixed frequency to convert the input voltage to a regulated output voltage. The output voltage can be adjusted using an internal voltage feedback control scheme and an external voltage divider connected between the BOOST/FB pins of the regulator. The regulator also includes a current limit circuit which protects the device from over current or short-circuit conditions.

Applications for the MP2161GJ-ZX include Point of Load (PoL) power supplies for processors and memory, voltage regulation for FPGAs and other power-sensitive applications, as well as power conversion for portable and battery-powered equipment. With its integrated synchronous buck converter, high efficiency, and excellent load and line transients, the MP2161GJ-ZX is well-suited to provide reliable, efficient power delivery to numerous applications.

The MP2161GJ-ZX is designed to provide high-efficiency, low-ripple voltage regulation across a wide input voltage range, with excellent line and load transients. With its low quiescent current and wide output voltage regulation, the MP2161GJ-ZX offers up to 6.0A of continuous switch current and an adjustable output voltage range of 0.8V to 5.5V.
