DESCRIPTION  
The TPS57140-Q1 device is a 42-V 1.5-A step-down regulator with an integrated high-side MOSFET.  
Current-mode control provides simple external compensation and flexible component selection. A low-ripple  
pulse-skip mode reduces the no load, regulated output supply current to 116 μA. Using the enable pin, shutdown  
supply current is reduced to 1.5 μA.  
Undervoltage lockout is internally set at 2.5 V, but can be increased using the enable pin. The output voltage  
startup ramp is controlled by the slow start pin that can also be configured for sequencing/tracking. An  
open-drain power good signal indicates the output is within 92% to 109% of its nominal voltage.  
A wide switching frequency range allows efficiency and external component size to be optimized. Frequency fold  
back and thermal shutdown protects the part during an overload condition.  
The TPS57140-Q1 is available in a 10-pin thermally enhanced MSOP PowerPADpackage (DGQ) and a  
10-pin SON package (DRC).
