DESCRIPTION  
The TPS43350-Q1 and TPS43351-Q1 include two current-mode synchronous buck controllers designed for the  
harsh environment in automotive applications. The part is ideally suited for a multi-rail system with low quiescent  
requirements, as the part automatically operates in low-power mode (consuming only 30 µA) at light loads. The  
part offers protection features such as thermal, soft-start, and overcurrent protection. During short-circuit  
conditions of the regulator output, the current through the MOSFETs can be limited for power dissipation by  
activation of the current foldback feature. The two independent soft-start inputs allow ramp-up of the output  
voltage independently during start-up.  
The switching frequency can be programmed over 150 kHz to 600 kHz or synchronized to an external clock in  
the same range. Additionally, the TPS43351-Q1 offers frequency-hopping spread-spectrum operation.
