The MIC2172BN is a DC-DC switching regulator designed for various applications, including boost, Cuk, flyback, and forward converter configurations. It features an internal switch rating of 1.25A and can handle input voltages ranging from 3V to 40V. The device operates at a frequency of 100 kHz and incorporates current mode operation with cycle-by-cycle current limiting for enhanced performance. This regulator is particularly suitable for battery-operated devices due to its low quiescent current of 7 mA during operation and less than 1 OºA in shutdown mode. The MIC2172BN supports external frequency synchronization and frequency trimming, making it ideal for applications requiring multiple regulators to operate from the same input supply without interference. It is available in an 8-pin plastic DIP package and is rated for operation in ambient temperatures from -40¬8C to +85¬8C.
