RT7271A  
6A, 17V, 500kHz CSP Synchronous Step-Down Converter  
General Description  
Features  
z 4.5V to 17V Input Voltage Range  
The RT7271Ais a high efficiency, synchronous step-down  
DC/DC converter for applications operating from 4.5V to  
17V and requiring up to 6A maximum load. The current  
mode architecture of RT7271A allows the transient  
response to be optimized. Cycle-by-cycle current limit  
provides protection against shorted output and soft-start  
eliminates input current surge during start-up. Fault  
conditions also include output under voltage protection,  
output over voltage protection, and thermal shutdown. The  
low current shutdown mode provides output disconnect,  
enabling easy power management in battery powered  
systems.
