The LM25010 features all the functions needed to implement a low cost, efficient, buck regulator capable of supplying in excess of 1A oad current. This high voltage regulator integrates an N-Channel Buck Switch, and is available in thermally enhanced LLP-10 and TSSOP-14EP packages. The constant on-time regulation scheme requires no loop compensation resulting in fast load transient response and implified circuit implementation. The operating frequency remains constant with line and load variations due to the inverse relationship between he input voltage and the on-time. The valley current limit detection is set at 1.25A. Additional features include: VCC under-voltage lock-ut, thermal shutdown, gate drive under-voltage lock-out, and maximum duty cycle limiter.
