Texas Instruments TPS54160 device is a 60V, 1.5A, 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 116mA. Using the enable pin, shutdown supply current is reduced to 1.3mA. It has a 3.5V to 60V input voltage range.
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 93% to 107% of its nominal voltage.
Among it s other features are the power MOSFET’s 200 mΩ on-resistance, 300 kHz to 2.5MHz switching frequency that allows optimization of efficiency and external component size, frequency foldback and thermal shutdown protect the part during an overload condition.
The TPS54160 is available in 10-pin thermally enhanced MSOP Power Pad package.
