PMIC (Power Management Integrated Circuits) is a type of electronic device designed to convert electric power into different forms in order to provide a stable voltage and/or current to other electronic components. Voltage regulators are one type of PMICs that are used to regulate the voltage across two or more points in a circuit. DC-DC switching regulators are a type of voltage regulator that use a switching output in order to provide an adjustable voltage from a variety of input sources. The ADP2147ACBZ-150-R7 is a DC-DC switching regulator from Analog Devices, Inc.

The ADP2147ACBZ-150-R7 is a single-phase step-down switching regulator with output current up to 1.5A. It has a wide input voltage range from 4.2V to 20V and a fixed-frequency peak current-mode control, allowing it to have fast transient response and excellent line and load regulation. It also provides good thermal performance with a Power OK signal, adjustable current limit, and Hiccup over-current protection. Additionally, the device features a low quiescent current (QI) of 19mA and high efficiency of up to 96% at full load.

The ADP2147ACBZ-150-R7 is designed to be used in a wide range of applications. It is suitable for use in general-purpose power supplies, computer peripherals, solar-powered systems, and automotive electronics. Additionally, the device can be used in high-current step-down conversion, such as powering embedded systems, data servers, telecoms, and PoE (Power over Ethernet) applications. The device can also be used in battery-powered systems.

The ADP2147ACBZ-150-R7 uses a pulse-width modulation (PWM) technique to regulate the output voltage. The device senses the peak inductor current of the voltage regulator and adjusts the duty cycle of the PWM signal to maintain the output voltage. The current limit is adjustable with the EN/SET pin, which allows the user to configure the output current limit. Additionally, the device features an enable pin (EN/SET) which can be used to turn the regulator off and on. In addition to output voltage regulation, the device also provides reverse current protection and soft start functionality.

The ADP2147ACBZ-150-R7 offers excellent thermal performance and is capable of operating at up to 116°F (47°C). The device is also EMI compliant and meets the CISPR22 Class B specifications. Additionally, the device is RoHS and MSL compliant, making it suitable for a wide range of applications.

Overall, the ADP2147ACBZ-150-R7 is an excellent choice for a wide range of DC-DC switching regulator applications. The device offers high efficiency, fast transient response, adjustable current limit, Hiccup over-current protection, and excellent thermal performance. In addition to these features, the device is also EMI compliant and MSL & RoHS compliant.
