FEATURES  
DESCRIPTION  
The TPS54531 is a 28-V, 5-A non-synchronous buck  
converter that integrates a low RDS(on) high side  
MOSFET. To increase efficiency at light loads, a  
pulse skipping Eco-mode™ feature is automatically  
activated. Furthermore, the 1 μA shutdown supply  
current allows the device to be used in battery  
powered applications. Current mode control with  
internal slope compensation simplifies the external  
compensation calculations and reduces component  
count while allowing the use of ceramic output  
capacitors. A resistor divider programs the hysteresis  
of the input under-voltage lockout. An overvoltage  
transient protection circuit limits voltage overshoots  
during startup and transient conditions. A cycle by  
cycle current limit scheme, frequency fold back and  
thermal shutdown protect the device and the load in  
the event of an overload condition. The TPS54531 is  
available in 8-pin SOIC PowerPADTM package that  
have been internally optimized to improve thermal  
performance.
