PMIC, or Power Management Integrated Circuit, is a separate integrated circuit that provides a variety of power management functions. Voltage regulators are one of the most important and most popular types of PMICs. DC DC switching regulators are one of the most common and efficient types of voltage regulators. PAM2400ACA270 is a DC DC synchronous buck switching regulator which is widely used in a variety of applications.

General Information

PAM2400ACA270 is a high performance, cost effective DC DC synchronous buck (step-down) switching regulator. It is capable of providing both 3A and 4A continuous output current at 1.2V to 5.5V output voltage with up to 92% efficiency. It has fast transient response, and because it is a synchronous buck regulator, it has minimal dropout performance. The switching frequency is adjustable, allowing it to be tailored to reduce EMI. The device is offered in a WL-CSP-6 package which is just 2.3mm x 2.2mm.

Application Field and Working Principle

PAM2400ACA270 has been applied in various applications, including but not limited to electronic products, power supplies, mobile devices, drones, connected home devices, IoT, and many more. It is widely used in applications in which a low-voltage output is required and rapid transient response is very important.The PAM2400ACA270 works as a synchronous buck regulator, which means that the output is connected directly to the ground through a MOSFET switch and a diode. The switch and diode both conduct alternately when the regulator is switched on and off, which is controlled by the internal Pulse Width Modulation (PWM) controller.The PWM controller controls the switching of the internal power MOSFET, supplying the output with a regulated voltage. The PAM2400ACA270 also has an adjustable frequency control and a power save mode, which can reduce the power consumption of the device.

Advantages

The PAM2400ACA270 has several advantages that make it an attractive solution for applications requiring a high-performance DC DC switching regulator.

• High efficiency up to 92%.
• A fast transient response time of 1.5µs.
• Low quiescent current of <50µA.
• High output current of 3A and 4A.
• Adjustable switching frequency.
• Minimum dropout operation.
• Compact design and small size of WL-CSP-6 package.

Conclusion

In conclusion, the PAM2400ACA270 is an ideal solution for a variety of applications which require a high-performance and cost-effective DC DC buck switching regulator. It has excellent efficiency, fast transient response, low quiescent current, and adjustable switching frequency. As it is offered in a tiny WL-CSP-6 package, it is also ideal for space-constrained applications.
