The MIC2183YM-TR is a high-efficiency PWM synchronous buck control IC designed by Microchip Technology. It offers a wide input voltage range from 2.9V to 14V, making it suitable for 1- or 2-cell Li-ion battery powered applications, as well as fixed 3.3V, 5V, or 12V systems. Efficiencies over 90% are achievable due to its PWM control scheme.
Key features include a nominal switching frequency of 400kHz, which can be divided by two for optimizing efficiency versus board space or synchronized externally. It also includes an oscillator output (FreqOut) for simple charge pump implementation in low voltage systems, a 1µA shutdown mode, and programmable undervoltage lockout, making it ideal for portable applications.
This IC is available in a 16-pin SOP and QSOP package options with a junction temperature range from -40°C to +125°C. The MIC2183YM-TR is designed for step-down applications, providing a positive output configuration with a single output phase. It supports synchronous rectification and features control functions like Enable, Frequency Control, and Soft Start.
Typical applications include voltage conversion from 3.3V to 2.5V/1.8V/1.5V, DC power distribution systems, wireless modems, ADSL line cards, 1- and 2-cell Li-ion battery operated equipment, and satellite phones.
