TPS54240 3.5-V to 42-V Step-Down DC - DC Converter

• 3.5-V to 42-V Input Voltage Range
> Description
The TPS54240 device is a 42-V, 2.5-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 138 μA. Using the enable pin, shutdown supply
current is reduced to 1.3 μA, when the enable pin is low.
Undervoltage lockout is internally set at 2.5 V, but it 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 and 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 optimization
of external component size. Frequency foldback and thermal shutdown
protects the part during an overload condition.
The TPS54240 is available in 10-pin, thermally-enhanced HVSSOP and
10-pin 3-mm x 3-mm PowerPAD package.
