Features

* include input undervoltage lockout, current limiting, and thermal shutdown. Features n n n n n n n n n n n n Ultra high efficiency up to 97% High efficiency over a 1.5A to milliamperes load range 4V to 14V input voltage range 1.8V, 2.5V, 3.3V, or ADJ output voltage Internal MOSFET switch with low R

Applications

* that demand long battery life in both run and standby modes. Synchronous rectification is used to achieve up to 97% efficiency. At light loads, the LM2651 enters a low power hysteretic or “sleep” mode to keep the efficiency high. In many applications, the efficiency still exceeds 80% at 15mA load. A
