Overview
Product Details
The ADP2147 is a high efficiency, low quiescent current, synchronous, step-down, dc-to-dc converter.The buck regulator automatically switches operating modes, depending on the load current level. At higher output loads, the buck regulator operates in PWM mode. When the load current falls below a predefined threshold, the regulators operate in power save mode (PSM), improving the light-load efficiency. The output voltage can be changed between two different settings under the control of a VSEL pin.
The 3 MHz switching frequency minimizes the size of external components.
