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
WSON-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.
