LM2653 1.
5A High Efficiency Synchronous Switching
Regulator
General Description
The LM2653 switching
regulator provides high efficient power conversion over a 100:1 load range (1.
5A to 15 mA).
This feature makes the LM2653 an ideal fit in battery-powered applications.
Synchronous rectification is used to achieve up to 97% efficiency.
At light loads, the LM2653 enters a low power hysteretic or “sleep” mode to keep the efficiency high.
In many applications, the efficiency still exceeds 80% at 15 mA load.
A shutdown pin is available to disable the LM2653 and reduce the supply current to 7µA.
