The MIC2290YML-TR is a high efficiency 2 MHz step-up DC/DC switching regulator designed for space constrained and low output voltage applications. It’s a high-frequency synchronous converter and integrated regulator, offering industry-leading accuracy and efficiency with minimal components. It also features a 100% duty cycle, allowing the device to generate an output voltage below the input voltage.

The device has an adjustable maximum output voltage and an adaptive voltage ramp which can reach up to 3A allowing the use of small inductors and capacitors. The output voltage can be adjusted easily thanks to Enable, Voltage Control and Synchronization pins.

Moreover, it has programmable output current and power up in standby function, allowing the device to be configured for different applications. The MIC2290YML-TR also includes thermal shutdown protection (TSD) and current limit protection (CLP).

The MIC2290YML-TR is well-suited for use in portable/handheld battery-operated products, as well as in various handheld/portable electronic devices such as smartphones, wearable devices and medical instruments.

The working principle of the MIC2290YML-TR is relatively simple: it takes the input voltage and converts it to a higher output voltage by means of a switching converter. The switching converter is a circuit composed of voltage regulation and power conversion. The voltage regulation stage serves to adjust the output voltage to the required level, while the power conversion stage serves to convert the voltage from one level to the other. The device uses a switch mode power supply (SMPS) to control the switching. The SMPS limits the input current of the device by shorting the input voltage as required, and uses switch mode technology to ensure a constant output voltage is maintained, even when the input voltage changes.

The MIC2290YML-TR offers an ideal combination of efficiency and low cost for space-constrained applications including but not limited to energy harvesting, sensors, portable medical, battery-powered applications, microcontrollers and TIUs, Bluetooth Low Energy and other communication technologies, process control and motor speed control, and active current limiting.

In conclusion, the MIC2290YML-TR is an efficient and cost-effective DC/DC switching regulator designed for low power operation in tight spaces. Its adjustable maximum output voltage, adaptive voltage ramp, programmable output current, and power up in standby functions make it a great choice for a variety of project applications.
