The MIC29201-4.8WT has a wide input voltage range and can deliver up to 4.8 Watts of output power. It is suitable for applications in computing systems, automotive, consumer electronic products, battery powered or green systems, industrial, healthcare and medical devices.

Application field

The MIC29201-4.8WT is an ideal solution for applications where maximum design flexibility is needed in a small space. It can be used in a variety of designs, including those used in computing systems such as laptop computers, tablets, and portable media players. It is also ideal for applications in automotive electronics and electric vehicles, consumer electronic products, battery operated or green systems, telecommunication systems, industrial and healthcare applications. In addition, the MIC29201-4.8WT can be used in applications where the system power demands require a high efficiency and financial constraints demand a low cost. The MIC29201-4.8WT module provides excellent efficiency at light loads, thus reducing system operating costs.

Working principle

The MIC29201-4.8WT is suitable for both step-up and step-down voltage regulation to provide an adjustable output voltage from 1.5V to 24V. It works on a linear regulation principle, which uses an internal error amplifier to sense the output voltage. The output voltage is adjusted by varying the control pin voltage input. The MIC29201-4.8WT delivers a low amount of current ripple, providing stable output voltage on all load conditions. The module contains an internal power switch with an externally controllable (ON/OFF) logic pin. An integrated soft-start circuit prevents inrush current while bringing up the output voltage. The module can withstand an input voltage up to 40V and is protected against output voltage overshoots.

Conclusion

The MIC29201-4.8WT is an excellent choice for applications requiring linear voltage regulation in a small space with high efficiency and low cost. Its wide input voltage range and adjustable output voltage make it suitable for various applications such as computing systems, automotive, consumer electronic products, battery operated systems, telecommunication systems, industrial and healthcare devices. In addition, the module contains an integrated power switch, a soft-start circuit and output voltage overshoot protection for reliability and ease of use.
