LM5017  
SNVS783I –JANUARY 2012–REVISED OCTOBER 2015  
LM5017 100-V, 600-mA Constant On-Time Synchronous Buck Regulator  
1 Features  
3 Description  
The LM5017 is a 100-V, 600-mA synchronous step-  
down regulator with integrated high side and low side  
MOSFETs. The constant on-time (COT) control  
scheme employed in the LM5017 requires no loop  
compensation, provides excellent transient response,  
and enables very high step-down ratios. The on-time  
varies inversely with the input voltage resulting in  
nearly constant frequency over the input voltage  
range. A high voltage startup regulator provides bias  
power for internal operation of the IC and for  
integrated gate drivers.

Adjustable Undervoltage Lockout (UVLO)  
Remote Shutdown  
A peak current limit circuit protects against overload  
conditions. The undervoltage lockout (UVLO) circuit  
allows the input undervoltage threshold and  
hysteresis to be independently programmed. Other  
protection features include thermal shutdown and  
bias supply undervoltage lockout (VCC UVLO).  
The LM5017 device is available in WSON-8 and  
HSOP PowerPAD-8 plastic packages.
