Original TPS57160QDGQRQ1 1.5-A 60-V Step-Down DC-DC Converter With Eco-mode Control 10-MSOP

Product Descriptions

The TPS57160-Q1 device is a 60-V 1.5-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, input supply current to 116 μA. Using the enable pin，shutdown supply current is reduced to 1.5 μA.

Undervoltage lockout is set internally at 2.5 V 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 or tracking. An open-drain power-good signal indicates the output is within 92 percent to 109 percent of the nominal voltage.

A wide switching frequency range allows efficiency and external component size to be optimized. Frequency foldback and thermal shutdown protects the part during an overload condition.

The TPS57160-Q1 device is available in a 10-pin thermally enhanced MSOP-PowerPAD™ (DGQ) or 10-pin VSON (DRC) package. The Z-suffix offers reduced delamination compared to standard device.
