The LM34910C Step Down Switching Regulator features all
of the functions needed to implement a low cost, efficient,
buck bias regulator capable of supplying 1.25A to the load.
This buck regulator contains a 55V N-Channel Buck Switch,
and is available in the thermally enhanced LLP-10 package.
The hysteretic 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 inverse relationship
between the input voltage and the on-time. The current
limit detection is set at 1.25A. Additional features include:
VCC under-voltage lockout, thermal shutdown, gate drive under-
voltage lockout, and maximum duty cycle limiter.
