Applications

The ADP2370ACPZ-1.8-R7 is well-suited for a wide range of applications, such as power conversion design, portable computing, embedded platforms and medical applications. In power conversion applications, it is used to provide a step-down regulated voltage from a higher input voltage. For example, it can be used to provide a 3.3V output from a 12V battery input. In portable computing applications, it can be used to provide low noise power to the CPU at a very low power draw. In embedded platforms, its low noise and high efficiency makes it an ideal choice for powering sensitive FPGA, microprocessor and memory devices. Finally, its low power requirements, integrated enable and power good features, and low operating temperature make it suitable for medical applications.

Working Principle

The ADP2370ACPZ-1.8-R7 operates in a constant frequency current-mode, pulse-width modulation (PWM) control. The current mode control provides excellent line and load transient response, while the constant frequency control eliminates the need for external compensation components. In addition, it provides protection against over-temperature, over current (using an internal power MOSFET current sense) and cross-conduction (using a dual-FET architecture).

The ADP2370ACPZ-1.8-R7 features external power MOSFETs that are turned on and off at a high frequency by the switching controller. An additional integrated power MOSFET senses the output current and provides current-limit protection. The output voltage is regulated by means of pulse-width modulation (PWM), which ensures accurate regulation by varying the duty cycle of the switching pulses. The PWM voltage control is adjusted by an external resistor.

The ADP2370ACPZ-1.8-R7 supports adjustable output voltage and over-temperature protection. The output voltage is adjusted via an external feedback resistor divider. The over-temperature protection feature limits the power dissipation by reducing the output voltage. This helps to protect the device from thermal overstress and improves the reliability of the system.

Conclusion

The ADP2370ACPZ-1.8-R7 is a stepdown switching regulator module capable of providing up to 6A of output current at an adjustable output voltage. It is suitable for a range of applications, including power conversion design, portable computing, embedded platforms, and medical applications. The ADP2370ACPZ-1.8-R7 operates in a constant frequency current-mode, pulse-width modulation (PWM) control to provide excellent line and load transient response, over-temperature protection, over current protection and cross-conduction protection. Overall, the ADP2370ACPZ-1.8-R7 is an ideal solution for creating reliable power conversion designs in a wide range of applications.
