The MIC3172YM is a 100 kHz DC-DC switching regulator designed for various applications, including laptop and handheld devices. It features an internal switch rating of 1.25A and operates within an input voltage range of 3V to 40V. The device supports current mode operation and includes an internal cycle-by-cycle current limit for enhanced reliability. The MIC3172YM is particularly suited for applications requiring enable/shutdown control, as it can be externally disabled with a TTL-low signal, reducing quiescent current to less than 1 OºA in shutdown mode. In normal operation, it draws only 7 mA of quiescent current, making it efficient for battery-powered applications. This regulator is compatible with various switching topologies, including boost, buck, and flyback configurations, and is available in an 8-pin plastic DIP or SOIC package, suitable for ambient temperatures ranging from -40¬8C to +125¬8C. The MIC3172YM is a viable option for engineers looking for a versatile and efficient switching regulator for their projects.
