The PAM2400AAA280 is a DC-DC switching regulator that provides the capability to switch voltages and current levels over a wide range. This voltage regulator is designed to provide a power supply with adjustable range, high efficiency, and smooth output. It is an innovative power management product that is ideal for a variety of integrated circuits (ICs). This article will discuss the application field and working principle of the PAM2400AAA280.

Application Field

The PAM2400AAA280 is suitable for microcontrollers, DSPs, FPGAs, ASICs, microprocessors, and other low power devices. Its extremely small size makes it suitable for use in limited space and allows for a very convenient installation inside the device. The design aims to provide a very low quiescent current consumption, which ensures a low power dissipation and improved system efficiency.

Additionally, the PAM2400AAA280 provides excellent voltage regulation and ripple characteristics, making it suitable for even the most sensitive applications. It features an input voltage range of 4.75V to 30V and an output voltage range of 0.95V to 14V, allowing for easy voltage level adjustments. The design also offers short-circuit and over-current protection.

Working Principle

The PAM2400AAA280 is a DC-DC switching voltage regulator that works on a switching frequency of 2.5MHz. It utilizes a pulse-width modulation (PWM) control to regulate the output voltage. The IC’s PWM control circuit samples the output voltage via a feedback pin and adjusts the duty cycle of the PWM switching cycle to provide the desired output voltage.

The PAM2400AAA280 is a synchronous buck regulator, meaning that transistors at both the input and output sides work together to transfer energy from the input side to the output side. The regulator uses external components to filter the input ripple and control the switching frequency.

The PAM2400AAA280 utilizes an internal low-dropout (LDO) regulator circuitry to generate an accurate reference voltage for the voltage loop control. This will allow for a much more reliable and stable output. Additionally, the IC provides an internal compensated current sensing circuit with programmable over-current protection.

Conclusion

The PAM2400AAA280 is a DC-DC switching voltage regulator designed for microcontrollers, DSPs, FPGAs, ASICs, and other low power devices. It features an input voltage range of 4.75V to 30V, an output voltage range of 0.95V to 14V, and a switching frequency of 2.5MHz. The design utilizes a PWM control circuit to regulate the output voltage, and provides a wide range of features such as over-current protection, short circuit protection, and accurate voltage regulation.
