LM5019 100-V, 100-mA Constant On-Time Synchronous Buck Regulator  
1 Features  
3 Description  
The LM5019 is a 100-V, 100-mA synchronous step-  
down regulator with integrated high-side and low-side  
MOSFETs. The constant-on-time (COT) control  
scheme employed in the LM5019 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.

Integrated 100-mA High-Side 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  
Adjustable Output Voltage from 1.225 V  
Precision 2% Feedback Reference  
Frequency Adjustable to 1 MHz  
Adjustable Undervoltage Lockout  
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.  
The LM5019 device is available in WSON-8 and SO  
PowerPAD-8 plastic packages.
