The MIC4681YM-TR is a 1A non-synchronous buck converter with a wide range of input voltage and excellent efficiency. It is a DC-DC switching regulator designed for easy and reliable integration into limited space applications. The low profile, wide input voltage and low power dissipation allow manufacturers to significantly reduce the cost of their applications.

The MIC4681YM-TR is an adjustable, step-down DC-DC converter that takes a high input voltage and reduces it to a lower voltage. It uses a high-efficiency synchronous MOSFET and a low-side switch along with an internal or external pass transistor to adjust the voltage. In order to reduce the many external components needed, the MIC4681YM-TR includes built-in compensation networks and a low-ripple current mode control with a fast transient response.

The MIC4681YM-TR provides a wide input voltage range of 4.2V to 18V, allowing it to be used in a variety of applications. It supports up to 1A of continuous current and can provide up to 4A of load transient current. The MIC4681YM-TR outputs adjustable voltage between +1.20V and +13.2V, with an output accuracy of ±2%. It also includes an output power good flag and thermal shutdown for system safety.

The MIC4681YM-TR\'s high level of efficiency also makes it suitable for battery-powered applications. Due to its wide input supply range, low quiescent current and low dropout voltage, the MIC4681YM-TR is ideal for use in space-restricted and portable electronic devices. Additionally, its integrated short-circuit and over-temperature protection ensure reliable power delivery in tough operational environments.
