5A High Efficiency Synchronous Switching Regulator February 2000 LM2651 1.
5A High Efficiency Synchronous Switching Regulator General Description The LM2651 switching regulator provides high efficiency power conversion over a 100:1 load range (1.
5A to 15mA).
This feature makes the LM2651 an ideal fit in battery-powered 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 shutdown pin is available to disable the LM2651 and red...
