MAX1823BEUB+T Application Field and Working Principle

The MAX1823BEUB+T is a voltage regulator housed in a tiny TDFN package that provides stepped up or down output voltages with adjustable current-limit protection. It can be tailored to both space-constrained and power-sensitive applications, such as portable electronics and embedded systems.

This power management device is designed to provide various output voltages with a wide range of input voltages and current demands. It can be used in both stepped down and step up applications, and is capable of handling 8V to 30V input range with 200mA to 1.8A of current. The output voltage of the device is adjustable to any voltage from 2.5V to 18V. It also has an adjustable peak current-limit protection with an acceptable over-current trip point of 6mA up to 115mA.

Application Fields

The MAX1823BEUB+T application fields include space-constrained and power-sensitive applications, such as in portable devices and embedded systems. It can be used as an adjustable step-up/step-down voltage regulator in both battery-powered and ac-powered applications, such as in hand-held devices, portable gaming and audio systems, notebook computers, wireless communication devices, and automotive and medical instrumentation.

Working Principle

The working principle of MAX1823BEUB+T relies on its internal synchronous buck (step-down) and boost (step-up) converter structure for a wide-input voltage range operation. The device includes a high-side N-Channel and a low-side N-Channel power MOSFETs that are operated in a synchronous buck-boost topology configuration.

The MAX1823BEUB+T features a logic-controlled 3-pin enable interface. This pin is used to activate/deactivate the device, allowing it to power up or down remotely, with a low active-high logic level to enable the device. Additionally, the device requires only a 1µF output capacitor with no inductors, making it simple to design and implement. Furthermore, it has short-circuit and over-current protection functions, as well as a soft-start ramp to reduce output-voltage inrush currents.

Conclusion

The MAX1823BEUB+T voltage regulator is an excellent choice for a range of space-constrained and power-sensitive applications. It is capable of providing adjustable stepped down or stepped up output voltage for a wide range of input voltages and current demands. Additionally, the device contains an adjustable peak current-limit protection and 3-pin enable interface that makes it easy to use and implement in a variety of systems.
