A Skipping Eco-mode™ Control Scheme low-ripple pulse-skip mode reduces the supply current to 116μA when outputting regulated voltage • 116-μA Operating Quiescent Current with no load. Using the enable pin, shutdown supply • 1.3-μA Shutdown Current current is reduced to 1.3μA when the enable pin is • 100-kHz to 2.5-MHz Switching Frequency low. • Synchronizes to External Clock Undervoltage lockout is internally set at 2.5 V, but • Adjustable Slow Start/Sequencing can be increased using the enable pin. The output voltage start-up ramp is controlled by the slow-start • UV and OV Power-Good Output pin that can also be configured for • Adjustable UVLO Voltage and Hysteresis sequencing/tracking. An open-drain power-good • 0.8-V ±3.5% Internal Voltage Reference signal indicates the output is within 94% to 107% of • MSOP10 With PowerPAD™ Package its nominal voltage. • Supported by WEBENCH A wide switching-frequency range allows efficiency and external component size optimization. Frequency 2 Applications foldback and thermal shutdown protect the part during an overload condition. • 12-V and 24-V Industrial and Commercial Low- Power Systems The TPS5401 is available in a 10-pin thermally enhanced MSOP PowerPAD package. • E-Meters (1) Device Information PART NUMBER PACKAGE BODY SIZE (NOM) TPS5401 MSOP (10) 3.00 mm × 3.00 mm (1) For all available packages, see the orderable addendum at the end of the datasheet.
