The HPA00695DRVR is a DC-DC switching regulator that falls under the category of voltage regulators, more specifically PMIC (Power Management Integrated Circuit). It is typically used in power management applications that require high efficiency and fast transient response. As such, its primary functions are to boost or step up input voltage as well as to generate negative output voltages.

This device comprises a synchronous, voltage mode, switching regulator control circuit combined with a low Rds(on) power MOSFET, which is primarily responsible for regulating output voltage with an output voltage range of 2.5 to 5 Volt. It’s capable of providing an output current up to 10A and has a 2MHz switching frequency. Additionally, the HPA00695DRVR operates at an input voltage range of 2.7V to 16V and has a low drop-out voltage of 200mV at a 10A load.

The HPA00695DRVR’s main features are its excellent transient response and high efficiency of up to 95%. It has a temperature range of -40°C to +85°C, making it suitable for a variety of operating conditions. It also has undervoltage and overvoltage protection. Additionally, it has the ability to provide up to 40mV ripple voltage, making it suitable for a range of different output voltages and current requirements. Moreover, it supports external synchronization, which allows it to be used in applications where noise mitigation is an essential consideration.

The HPA00695DRVR is primarily used in buck and boost applications in power management systems such as smartphones, tablets, laptops, IoT devices, wearable electronics, and servers. It excels in applications where efficiency and performance have to be balanced and allows the user to adjust the parameters such as the output voltage, current, switching frequency and synchronization.

Working Principles

The HPA00695DRVR is designed with a voltage mode control and synchronous rectification, which ensures a fast response to changes in load or input conditions. It also features a user-selectable power saving mode and soft-start features. When powered, the HPA00695DRVR starts to detect the input voltage and decides the conditions of all components. It then outputs the signal to the external P-channel MOSFET, which begins to regulate the output voltage and current. When the external MOSFET is fully saturated, the voltage between the output pin and the input pin will be lower than the set point, and provides enough power for the external loads.

In addition, the HPA00695DRVR automatically switches between synchronous and diode rectification, depending on the load requirement. When the load is higher, it will switch from diode rectification to synchronous rectification to increase conversion efficiency. On the other hand, when the load is lower, it will switch from synchronous rectification to diode rectification to reduce switching losses.

Conclusion

The HPA00695DRVR is a versatile DC-DC switching regulator that can be used in a variety of applications where power efficiency and high performance are the main considerations. As such, it provides an excellent solution for those who want to ensure their device’s battery life, while still providing the necessary power needed for the application in question. It boasts a range of features, such as excellent transient response, fast switching, and low drop-out voltage, which can make it an ideal choice for many applications.
