ADP5023ACPZ-R7 Integrated Circuits (ICs)

The ADP5023ACPZ-R7 is an integrated linear and switching voltage regulator that has been specifically designed to simplify power management systems in both cost and space. It is a high precision solution that provides a wide range of dynamic performance requirements and adaptability. The regulator is ideal for applications such as mobile phones, tablets, mid-range and low-end computing, TVs, appliances, Netbooks, and more.

At the heart of the regulator is its control loop, which drives the high-side and low-side high-transient voltage switches. The two switches in combination with the rectifier and low-drop linear regulator provide a very precise output voltage regulation from 0.7V to 5.500V. The control loop continuously monitors the feedback pin voltage and adjusts the feedback pin voltage by modulating the buck converter and linear regulator in synchronicity with each other.

The benefit of the combination of the two regulator implementations is that very low output voltage ripple is achieved, allowing for a more precise regulated output voltage. This makes the ADP5023ACPZ-R7 an ideal choice for applications that require tight voltage control and load transient response. By taking advantage of its adaptive loop frequency, the regulator can be optimized to maintain the optimum response characteristics, even when the load or voltage source changes.

The ADP5023ACPZ-R7 also integrates three levels of overcurrent protection. Two level of overcurrent protection are available on the high side and one is available on the low side. The overcurrent protection is integrated into the reference voltage block, which allows the support of a wide variety of load currents and output voltages. This combination of overcurrent protection and voltage control make the ADP5023ACPZ-R7 an ideal choice for a wide range of power management applications.

The ADP5023ACPZ-R7 also features adjustable soft-start and slew-rate control. This allows for precise power-on ramp up and protection against inrush current during turn-on. The slew-rate control ramps up the output voltage slowly over a specified period of time.

Aside from the amplitude control, the ADP5023ACPZ-R7 also provides thermal shutdown, external shutdown, enable/disable, and synchronization. The enable/disable allows external circuits to shut down the regulator when not in use or when the operation is no longer required. It also provides synchronization with external clock sources to provide the precise output voltage needed in time-sensitive applications. Additionally, the regulator is also equipped with an accurate power-on reset function, which ensures that the voltage is stable and in line with the specified range upon power on.

The ADP5023ACPZ-R7 is the perfect solution for a host of power management applications. Its combination of linear and switching voltage regulation provides exceptional precision, while its various protection and enable functions ensure a safe and reliable system. With its easy-to-implement control loop, adjustable slew rate and smooth operation, the ADP5023ACPZ-R7 is the ideal choice for today’s power management systems.
