MIC5281-5.0YMME is a synchronous buck regulator, belonging to Power Management IC (PMIC) and providing 6A continuous output current. It belongs to the Linear Regulators category of Voltage Regulators. It is designed by Micrel and is a low dropout regulator that efficiently regulates an output voltage from as low as 0.6 V to a maximum of 5 V. It uses FETs as the main device, and synchronous rectification to enable higher power efficiency and reduce power losses. It can be used in a wide range of applications, such as variable load systems and battery powered or USB powered devices.This IC requires a minimum 4.4V for its operation. It features advanced power sequencing, wide voltage range of 0.8V to 5.5V, fast switching frequency up to 1MHz and adjustable current limit protection. The dropout voltage of this device is 50mV (max) making it very efficient in operation. The output current can be limited to a maximum of 5A at any given time. This IC also features soft start and thermal shutdown, under-voltage lockout, output voltage accuracy of ±2%, and over current protection. Its design also has 100% duty cycle capability which enhances its efficiency.This device is available in the MSOP-8 package. It has an input operating temperature range of -40°C to +85°C, while the output operating voltage range is -40°C to +125°C. It also has a Inrush Current Limit of 15A, and a high power dissipation capability of 0.89W. It is built from low resistance power MOSFETS, and features a high or low side Sense pin for fast response to load transients. The MIC5281-5.0YMME also features an internal loop compensation, adjustable voltage reference (programmable startup voltage, adding hysteresis) and adjustable frequency (200kHz to 1MHz).The MIC5281-5.0YMME synchronous buck regulator can be used for many applications such as powering cellular phones, portable electronic equipment, DC/DC converters and other battery poweredportable devices. It is a highly efficient device, with fast, adjustable voltage switching and programmable power sequencing. It is great for eliminating switching noise, reducing power loss and increasing system efficiency.The MIC5281-5.0YMME uses synchronous rectification to reduce power losses and increase efficiency. This works by using both the high and low side FETs to switch when the output voltage is needed and only using the high side FET to allow current to flow into the VOUT when the output voltage drops, allowing the low side FET to remain off and turn on as needed. This reduces losses compared to regular PWM switching, especially when the output voltage is varied or loaded.The MIC5281-5.0YMME also features an adjustable current limit. This limit restricts the amount of current that can flow through the IC, typically in order to protect components from overcurrent situations. This is adjustable via the output voltage, allowing the current limit to be set to suit the application.Finally, the MIC5281-5.0YMME features an internal loop compensation. This allows the device to better adjust to changes in load, by allowing the feedback loop of the regulator to follow load transients faster. This helps to reduce output voltage ripple and provide for greater stability in applications.In summary, the MIC5281-5.0YMME synchronous buck regulator is a low dropout, current limited, high efficiency and fast switching device, ideal for powering systems that require high efficiency and low power loss. It can be used for many applications, from cellular phones, to portable electronic equipment and DC/DC converters. This device features programmable power sequencing, adjustable voltage reference, adjustable frequency, adjustable current limit, soft start, over current protection and thermal shutdown. Its combination of features make the MIC5281-5.0YMME an excellent choice for those looking for a reliable, efficient power solution.
