DESCRIPTION  
The TPS40056 is part of a family of high-voltage,  
wide input, synchronous, step-down converters.  
The TPS40056 offers design flexibility with a  
variety of user programmable functions, including  
soft-start, operating frequency, high-side current  
limit, and loop compensation. The TPS40056 is  
also synchronizable to an external supply. It  
incorporates MOSFET gate drivers for external  
N-channel high-side and synchronous rectifier  
(SR) MOSFETs. Gate drive logic incorporates  
anti-cross conduction circuitry to prevent  
simultaneous high-side and synchronous rectifier  
conduction. The externally programmable short  
circuit protection provides pulse-by-pulse current  
limit, as well as hiccup mode operation utilizing an  
internal fault counter for longer duration  
overloads.
