DescripTion  
TheLTC®7801isahighperformancestep-downswitching  
regulator DC/DC controller that drives an all N-channel  
synchronous power MOSFET stage that can operate from  
input voltages up to 140V. A constant frequency current  
mode architecture allows a phase-lockable frequency of  
up to 850kHz.

Onboard LDO or External NMOS LDO for DRV  
The gate drivevoltage can beprogrammed from 5V to10V  
to allow the use of logic or standard-level FETs to maxi-  
mize efficiency. An integrated switch in the top gate driver  
eliminates the need for an external bootstrap diode. An
