MIC2194YM Description

Short technical summary and product information.

The MIC2194YM from Microchip Technology is a high-efficiency PWM buck control IC housed in a space-saving 8-SOIC package. Its flexible architecture allows it to be configured as a buck or a buck-boost converter, making it suitable for various power supply designs.

 

This IC features a wide input voltage range of 2.9V to 14V, enabling efficient voltage step-down in 3.3V, 5V, and 12V systems, as well as in 1- or 2-cell Li-Ion battery-powered applications. The 400kHz PWM operation allows for the use of small inductors and output capacitors, and it can implement all-ceramic capacitor solutions.

 

The MIC2194YM drives a high-side P-channel MOSFET and offers a low output driver impedance of 2Ω. It supports a maximum duty cycle of 100%, which is beneficial for low headroom applications. The device also includes features such as programmable UVLO, front edge blanking, cycle-by-cycle current limiting, and frequency foldback short circuit protection.

 

Designed for surface mount, the MIC2194YM operates within a junction temperature range of -40°C to +125°C. Its compact SO-8 package and low pin count minimize external component requirements and save valuable board space.
