MIC2875-5.25YMT-TR

PMIC - Voltage Regulators - DC DC Switching Regulators

The MIC2875-5.25YMT-TR is a high-performance voltage regulator chip that is designed for ultra-portable applications. It is a 5.25 A (5A peak current) DC-DC switching regulator that operates at an output voltage of 3.3V or 5V. The MIC2875-5.25YMT-TR is manufactured by Microchip Technology.

Application Field

The MIC2875-5.25YMT-TR is ideally suited for battery-powered portable devices such as notebook computers, digital cameras and PDAs. It can also be used in other applications that require a low voltage and low power supply. The MIC2875-5.25YMT-TR is designed to be used in tight spaces as it has a very small overall size and low power dissipation.

Working Principle

The MIC2875-5.25YMT-TR is a hybrid buck/boost regulator. The voltage input is regulated using either a buck (step-down) or boost (step-up) converter depending on the input voltage. The buck converter is used when the input voltage is higher than the output voltage, while the boost converter is used when the input voltage is lower than the output voltage. The chip uses a wide input voltage range (2.7V to 5.5V) and is capable of providing a regulated output for both high and low input levels.

The MIC2875-5.25YMT-TR is designed to provide up to 5A of current with a high efficiency of up to 90%. The switch frequency of the regulator is 1.2 MHz and can be adjusted according to the application. The chip also has an adjustable soft-start feature to prevent overshoots at startup. The MIC2875-5.25YMT-TR is protected against over-temperature, over-current and over-voltage.

The MIC2875-5.25YMT-TR is available in a 6-pin SOT-23 package. The chip has been designed with minimized external components to reduce board space. Additionally, the MIC2875-5.25YMT-TR has an integrated thermally-enhanced package to improve thermal performance.
