DESCRIPTION  
The TPS54240-Q1 device is a 42V, 2.5A, 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 138μA. Using the enable pin, shutdown supply  
current is reduced to 1.3μA, when the enable pin is low.  
Under voltage lockout is internally set at 2.5V, 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 94% to 107% 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 TPS54240-Q1 is available in 10 pin thermally enhanced MSOP Power Padpackage.
