产品概述 返回TOP
The CXSD62179 is a high efficiency monolithic synchronous buck regulator. CXSD62179 operates with a constant 1.5MHz switching frequency and using the inductor current as a controlled quantity in the current mode architecture. The 2.7V to 5.5V input voltage range makes the CXSD62179 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 use of small surface mount inductors and capacitors. The synchronous switches included inside increase the efficiency and eliminate the need for an external Schottky diode. The CXSD62179 is available in TSOT-23-6A package
