The function LM34910C step of this switching regulator requires all the features of a low-cost, high-efficiency, buck-bias regulation that provides a load capacity of 1.25A. This buck regulator contains a 55V N-channel buck switch and is available in a thermally enhanced LLP-10 package. Regulatory lag, no loop compensation, fast load transient response results, and simplified circuit design. The operating frequency still varies with the line and load, due to the inverse relationship between the input voltage and the on-time. The current limit test is set at 1.25A. Other features include: VCC undervoltage lockout, overheat shutdown, gate drive undervoltage lockout, and maximum duty cycle limit.
