MIC2185YQS-TR Description

Short technical summary and product information.

The MIC2185YQS-TR from Microchip Technology is a high-efficiency synchronous boost PWM control IC. It is designed for applications requiring voltage boosting from sources like 1- or 2-cell Li-Ion batteries or fixed 3.3V and 5V systems.

 

Key electrical specifications include an input voltage range of 2.9V to 14V and an operating frequency of 400kHz, with the capability for frequency synchronization up to 600kHz. The device features a low shutdown current of 0.5µA and includes control features such as Enable, Frequency Control, and Soft Start.

 

This IC is suitable for noise-sensitive telecommunications applications due to its fixed-frequency PWM architecture and synchronized drive. It is available in a 16-pin QSOP package and operates within an ambient temperature range of -40°C to 85°C.

 

The MIC2185YQS-TR is designed for surface mount applications and offers a positive output configuration. Its topology is Buck, with a maximum duty cycle of 100%.
