DESCRIPTION
The TPS54240 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 138mA. Using the enable pin, shutdown supply current is
reduced to 1.3mA, 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 is available in 10 pin thermally enhanced MSOP Power Pad package.
