The MIC69303YME-TR is an IC component that belongs to the MIC69303 series of voltage regulators produced by Microchip Technology Inc. This particular IC is a synchronous buck regulator with an input voltage range from 4.5V to 16V. It offers a fixed output voltage of 3.3V with a maximum output current of 3A.
One of the key features of the MIC69303YME-TR is its high efficiency, thanks to its synchronous operation and internal low-resistance MOSFETs. It utilizes a pulse-width modulation (PWM) control scheme to provide precise output voltage regulation. The IC also includes an adjustable soft-start feature, allowing for controlled startup and shutdown sequences.
To ensure system reliability, this IC component offers a wide range of protection features. It incorporates thermal shutdown, overcurrent protection, and undervoltage lockout functionalities. The thermal shutdown feature prevents the IC from overheating, while the overcurrent protection safeguards against excessive current flow. The undervoltage lockout function prevents the IC from operating when the input voltage falls below a certain threshold, ensuring protection against brownout conditions.
The MIC69303YME-TR is available in a small 3x3mm, 16-pin QFN package, making it ideal for space-constrained applications. Its high-frequency operation enables the use of compact external components
