MIC2202-1.5BML-TR application field and working principle

MIC2202-1.5BML-TR is a DC DC switching regulators which are a type of switching power supply, used for creating a steady output voltage from a variety of inputs, including unregulated AC and DC voltage signals. The MIC2202-1.5BML-TR is specifically targeted for applications with up to 1.5 Amp load power requirements, such as notebooks, wearable devices, and cellular phones, where space and weight are at a premium.

Working Principle

DC DC switching regulators use the principles of switched-mode power supply (SMPS) in order to regulate an input voltage to any required output voltage. The MIC2202-1.5BML-TR can use either a voltage source or a current source as an input source. When an AC input source is used, the SMPS converts it to a DC voltage by creating a bridge rectifier circuit. The output will then be controlled by a feedback loop circuit, which constantly adjusts the duty cycle of the switching device (in this case, the MIC) to maintain the output voltage. Any power dissipation due to the output voltage being higher than the input voltage will be dissipated in the switching transistor itself, making it less suitable for higher power applications. The SMPS operates in constant frequency and pulse width modulation modes, which allow for better power conversion efficiency and noise reduction.

Application Field

The MIC2202-1.5BML-TR is suitable for a range of DC DC switching regulator applications within the 1.5 Amp load power limit, such as wearables, notebooks, cell phones, industrial control components, embedded systems, and similar. Moreover, it can provide regulated power outputs of up to 1.5 Amp in a very small package which produces little to no heat. This makes it ideal for applications where size and weight are at a premium, such as wearable devices and mobile phones.The MIC2202-1.5BML-TR has a wide input voltage range of 2.5V to 28V, which makes it adaptable to a wide range of input sources. It provides an adjustable output voltage range from 0.8V to 27V with a maximum efficiency of 95%. It also includes adjustable soft-start, under voltage lockout (UVLO), temperature protection, and over current protection, making it a safe and reliable power solution for applications.

Conclusion

The MIC2302-1.5BML-TR DC DC switching regulator is a highly efficient and low-power solution for a wide range of applications that require up to 1.5 Amp power loads. It has a wide input voltage range and adjustable output voltage range with a maximum efficiency of 95%. It also features adjustable soft-start, under voltage lockout (UVLO), temperature protection, and over current protection, making it a safe and reliable power solution. The MIC2202-1.5BML-TR is an ideal power solution for wearables, notebooks, cell phones, embedded systems, and other applications where size and weight are at a premium.
