The LM34910 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 40V 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.
