Description
General part information
LM2653 Series
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.
All the power, control, and drive functions are integrated within the ICs. The ICs contain patented current sensing circuity for current mode control. This feature eliminates the external current sensing resistor required by other current-mode DC-DC converters.
