2 Overview
2.1 LM5013-Q1 Asynchronous Buck Converter
The LM5013-Q1 step-down switching converter features all the functions needed to implement a low-cost,
high-efficiency buck regulator capable of supplying 3.5-A load current. An adaptive constant on-time (COT)
control scheme and PFM at light loads enables low standby current. Various features incorporated for enhanced
reliability and safety include cycle-by-cycle peak current limit, thermal shutdown protection, internal output
voltage soft-start timer, precision enable , and an open-drain PGOOD indicator for sequencing and fault
reporting.
Figure 2-1 shows the pin configuration of the LM5013-Q1. Figure 2-2 presents the regulator schematic for quick
reference.
