LM5017  
100V, 600mA Constant On-Time Synchronous Buck  
Regulator  
General Description  
Features  
The LM5017 is a 100V, 600mA synchronous step-down reg-  
ulator 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 low 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.  
Wide 9V to 100V Input Range  
Integrated 100V, High and Low Side Switches  
No Schottky Required  
Constant On-time Control  
No Loop Compensation Required  
Ultra-Fast Transient Response  
Nearly Constant Operating Frequency  
Intelligent Peak Current Limit  
A peak current limit circuit protects against overload condi-  
tions. The undervoltage lockout (UVLO) circuit allows the  
input undervoltage threshold and hysteresis to be indepen-  
dently programmed. Other protection features include ther-  
mal shutdown and bias supply undervoltage lockout (VCC  
UVLO).  
Adjustable Output Voltage from 1.225V  
Precision 2% Feedback Reference  
Frequency Adjustable to 1MHz  
Adjustable Undervoltage Lockout (UVLO)  
Remote Shutdown  
The LM5017 is available in LLP-8 and PSOP-8 plastic pack-  
ages.
