TPS57060QDRCRQ1

The TPS57060-Q1 is a 60V, 0.5A step-down regulator with an integrated high-side MOSFET. Current-mode control provides simple external compensation and flexible component selection. Low-ripple pulse skip mode reduces no-load quiescent current to 116μA. When the enable pin is pulled low, shutdown current drops to 1.3μA. The UVLO voltage is internally set to 2.5V but can be raised using the enable pin. The output voltage startup ramp is controlled by the soft-start pin, which can also be used for sequencing and tracking configuration. An open-drain power-good signal indicates that the output is within 92% to 109% of its nominal voltage. The wide switching frequency range allows optimization of efficiency and external component size. Frequency foldback and thermal shutdown protect the device under overload conditions. The TPS57060-Q1 is available in a 10-pin thermally enhanced MSOP-PowerPAD (DGQ) package and a VSON (DRC) package.
