DescriptionThe LM5010Ax step-down switching regulatoris an
enhanced version of the LM5010 with the input
operating range extended to 6-V minimum. The
LM5010Ax features all the functions needed to
implement a low-cost, efficient, buck regulator
capableof supplyingin excessof 1-A load current.
This high-voltage regulator integrates an N-Channel
Buck Switch, andis availablein thermally enhanced
10-pin WSON and 14-pin HTSSOP packages. The
constant ON-time regulation scheme requiresno loop
compensation resulting in fast load transient
response and simplified 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
valley current limit detection is set at 1.25 A.
Additional features include: VCC undervoltage
lockout, thermal shutdown, gate drive undervoltage
lockout, and maximum duty cycle limiter.
