LM34919 Ultra Small 40V, 600 mA Constant On-Time Buck Switching
Regulator
General Description
The LM34919 Step Down Switching
Regulator features all of the functions needed to implement a low cost, efficient, buck bias
regulator capable of supplying 0.
6A to the load.
This buck
regulator contains an N-Channel Buck Switch, and is available in a micro SMD package.
The constant on-time feedback regulation scheme requires no loop compensation, results in fast load transient response, and simplifies circuit implementation.
The operating frequency remains constant with line and load variations due to the inver...
