LM34914 - Ultra Small 1.25A Step-Down Switching Regulator
National Semiconductor (now Texas Instruments)
General Description
The LM34914 Step-Down Switching Regulator
Key Features
all the functions needed to implement a low cost, efficient, buck bias regulator capable of supplying at least 1.25A to the load. To reduce excessive switch current due to the possibility of a saturating inductor the valley current limit threshold changes with input and output voltages, and the on-time is reduced when current limit is detected. This buck regulator contains a 44V N-Channel Buck Switch, and is available in the thermally enhanced 3 mm x 3 mm LLP-10 package. The feedback regulation.
