CXLE8164 is a 1.5MHz high efficiency monolithic synchronous buck regulator. Design with current mode scheme, the CXLE8164 is stable with ceramic output capacitor. Input voltage from 3V to 5.5V makes the CXLE8164 ideally suited for single Li-Ion battery powered applications. 100% duty cycle provides low dropout operation, extending battery life in portable electrical devices. The internally fixed 1.5MHz operating frequency allows the using of small surface mount inductors and capacitors. The synchronous switches included inside increase the efficiency and eliminate the need of an external Schottky diode. The CXLE8164 is available in SOT-23-5/TSOT-23-5A packages
