The LM34910 Step Down Switching Regulator features all ofthe funcTIons needed to implement a low cost, efficient, buckbias regulator capable of supplying 1.25A to the load. Thisbuck regulator contains a 40V N-Channel Buck Switch, andis available in the thermally enhanced LLP-10 package. ThehystereTIc regulaTIon scheme requires no loop compensaTIon,results in fast load transient response, and simplifiescircuit implementation. The operating frequency remainsconstant with line and load variations due to the inverserelationship between the input voltage and the on-time. Thecurrent limit detection is set at 1.25A. Additional featuresinclude: VCC under-voltage lockout, thermal shutdown, gatedrive under-voltage lockout, and maximum duty cycle limiter.
