LM34917A Overview
Key Specifications
Mount Type: Surface Mount
Pins: 12
Operating Voltage: 33 V
Min Voltage (typical range): 8 V
Description
The LM34917A Step-Down Switching Regulator 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.
Key Features
- Transient Capability to 50V
- Integrated N-Channel buck switch
- Valley current limit varies with VIN and VOUT to reduce excessive inductor current
- On-time is reduced when in current limit
- Integrated start-up regulator
