ADP2118ACPZ-R7 is an advanced, monolithic, synchronous buck regulator designed for use in a variety of consumer and applications. As part of the PMIC family of voltage regulators, the DC DC switching regulator offers high efficiency and fast transient response, making it suitable for power solutions in both mobile and industrial fields.

The ADP2118ACPZ-R7 operates with a 4.5V to 36V input voltage, and a 3V to 10V adjustable output voltage. It is a true synchronous buck regulator, using a MOSFET switch to provide efficiency up to 94%. The switching frequency can be adjusted between 200KHz and 1.4MHz, and voltage mode control is implemented for stable loop gain. The device also features an enable pin for shutdown and pulse skipping for light load conditions, allowing for fast transient responses. The PWM dimming feature allows for a wide range of output voltage adjustments, where the output current can be up to 4A.

One of the main advantages of the ADP2118ACPZ-R7 is its low RDSon, with a very low Gate charge to provide exceptional efficiency. This is complemented with multiple current protection, along with thermal shutdown, over current protection, and over load foldback functions. The combination of fast transient responses, stable loops and high efficiency make the ADP2118ACPZ-R7 an ideal solution for a wide range of applications.

The ADP2118ACPZ-R7 can be used in many industries and applications. It is particularly suitable for battery-powered applications, since it can maintain power efficiency when the input voltage is changing. Traditional solutions rely on linear regulators for low power designs, however the ADP2118ACPZ-R7 DC DC switching regulator can provide better efficiency and higher power density. One example of this is handheld test equipment, where it can be used to supply a reliable power source. It can also be used in automotive solutions, such as in engine control modules, traction control systems and dashboard displays.

In addition, the ADP2118ACPZ-R7 is also suitable for industrial applications, where the robust features mean it can be used in harsh working environments. It can supply power for distributed power architecture, and is capable of powering multiple loads simultaneously. It is also an ideal solution for powering high-performance FPGAs, GPUs and modems.

The working principle of the ADP2118ACPZ-R7 is based on a two-level topology, with a MOSFET switch connected to an inductor and the output. The switch is controlled by an internal oscillator, which sets the operating frequency; this is then controlled by a voltage loop, with the operand voltage being compared to the feedback voltage. This is the basis of the PWM dimming feature; when the input voltage or load current changes, the voltage is adjusted to maintain the output voltage.

The combination of features, along with the wide range of applications, make the ADP2118ACPZ-R7 an ideal choice for modern power solutions. It offers excellent performance, making it suitable for both industrial and mobile applications, and provides the flexibility to be configured for a range of operating conditions. With its fast transient response, efficient design and robust features, the ADP2118ACPZ-R7 is the perfect choice for reliable, high-performance power solutions.
