DESCRIPTION The TPS54060 device 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. 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, when the enable pin is low. FEATURES • 3.5V to 60V Input Voltage Range • 200-mΩ High-Side MOSFET • High Efficiency at Light Loads with a Pulse Skipping Eco-Mode™ • 116mA Operating Quiescent Current • 1.3mA Shutdown Current • 100kHz to 2.5MHz Switching Frequency • Synchronizes to External Clock • Adjustable Slow Start/Sequencing • UV and OV Power Good Output • Adjustable UVLO Voltage and Hysteresis • 0.8-V Internal Voltage Reference • MSOP10 and 3mm x 3mm SON Package With PowerPAD™
The TPS57060-Q1 device is a 60-V 0.5-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 116 μA. When the enable pin is in the low state, the shutdown current is reduced to 1.3 μA. Undervoltage lockout is internally set 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 and tracking. An open-drain power good signal indicates the output is within 92% to 109% of the 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 TPS57060-Q1 device is available in a 10-pin thermally enhanced MSOP-PowerPAD package (DGQ) and a VSON (DRC) package.
