MAX5035DASA/V+T, also referred to as DC-DC switching regulator, is a PMIC (or power management integrated circuit) voltage regulator designed to provide a regulated power supply to the circuit. The device has a wide application field and can work in many different conditions.

Application Field

MAX5035DASA/V+T is particularly suitable for battery-powered applications such as smart phones and tablets, portable speakers and portable electronics. The DC-DC switching regulator output voltage can be easily adjusted from 8 V to 40 V, typically supporting input voltage of up to 40 V. This makes it possible to operate from a wide range of voltages including 3V Lithium-ion, 4V Alkaline battery and 3.7V to 4.2V Li-ion battery. In addition, the maximum load capability of 5 A makes this device suitable for powering high load applications such as ultra-high definition audio systems or high performance designs. The robust design of this device also allows it to provide a reliable voltage in even the most demanding power environment.

The low dropout (LDO) feature of MAX5035DASA/V+T enables the device to maintain a reliable and steady voltage even when the input voltage varies. This feature is also useful for battery-powered applications as it helps to minimise the power losses of the device and minimises battery drain, thus providing an energy-efficient and cost effective solution. In addition, the device can also be used for high current applications such as automotive systems, telecommunications, industrial and telecom power.

The device also comes with an advanced protection system which provides protection against overvoltage, overcurrent, and excessive heat. The built-in protection circuit also protects the device from thermal runaway and allows it to run safely in the harshest environments.

Working Principle

The MAX5035DASA/V+T works on the principle of DC-DC switching converter. The device consists of an integrator, a power switch, a feedback loop and a feedback network. The power switch is responsible for turning the device on and off, while the feedback network and the integrator work together to provide the necessary feedback to regulate the output voltage based on the input voltage applied to the device.

When the switch is on, the current flows through the inductor, the output capacitor and the internal transistor, into the system load. The current passing through this circuit charges the output capacitor and thus provides power to the system. Once the transistor is turned off, the output voltage is regulated by the feedback network. The integrator then processes the information from the feedback network, and alters the switching frequency accordingly, so that the desired output voltage is maintained.

The MAX5035DASA/V+T offers a high efficiency level of up to 95%. This is made possible by its integrated power switch, the ability to adjust the switching frequency, and its ability to use low dropout (LDO) capability to mitigate voltage drops. In addition, the device features adjustable voltage limiters, a built-in protector circuit, and a high-efficiency output stage.

Conclusion

The MAX5035DASA/V+T DC-DC switching regulator is a high-performance PMIC voltage regulator. It has a wide application field, allowing it to be used for various battery-powered, automotive, industrial and telecom applications. In addition, it also features an advanced protection system and low dropout capability to protect the device from excessive voltages and overheating. Furthermore, its high efficiency of up to 95% makes it an ideal choice for energy-efficient solutions.
