The MIC2183YQS from Microchip Technology is a high-efficiency PWM synchronous buck control IC designed for stepping down voltages. With a broad input voltage range from 2.9V to 14V, it is suitable for 1- or 2-cell Li-ion battery powered applications, as well as fixed 3.3V, 5V, or 12V systems.
This IC utilizes a PWM control scheme to achieve efficiencies over 90% across a wide load range. It offers a nominal operating frequency of 400kHz, with an option to divide the frequency by two for optimizing efficiency versus board space or for external synchronization. The device includes features like a 1 µA shutdown mode and programmable undervoltage lockout, making it well-suited for portable applications.
The MIC2183YQS is available in a 16-QSOP package and supports surface mount installation. Its control features include Enable, Frequency Control, and Soft Start, along with cycle-by-cycle current limiting and frequency foldback short circuit protection. The operating temperature range is -40°C to 85°C (TA).
Key electrical specifications include a 2.9V to 14V input voltage range, a maximum duty cycle of 100%, and a single positive output configuration. It also features a synchronous rectifier and clock synchronization capabilities.
