DESCRIPTION  
The LM25017 is a 48V, 650mA synchronous step-down regulator with integrated high side and low side  
MOSFETs. The constant-on-time (COT) control scheme employed in the LM25017 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.  
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 LM25017 is available in LLP-8 and PSOP-8 plastic packages.
