Low as 0.9 V, Operating Down to 0.8 V The converter output voltage can be adjusted from • 200-mA Output Current From 0.9-V Supply 1.5 V to a maximum of 3.3 V, by an external resistor • Powersave-Mode for Improved Efficiency at Low divider or, is fixed internally on the chip. The devices Output Currents provide an output current of 200 mA with a supply voltage of only 0.9 V. The converter starts up into a • Autodischarge Allows to Discharge Output full load with a supply voltage of only 0.9 V and stays Capacitor During Shutdown in operation with supply voltages down to 0.8 V. • Device Quiescent Current Less Than 50 μA The converter is based on a fixed frequency, current • Ease-of-Use Through Isolation of Load From mode, pulse-width-modulation (PWM) controller that Battery During Shutdown of Converter goes automatically into power save mode at light • Integrated Antiringing Switch Across Inductor load. It uses a built-in synchronous rectifier, so, no • Integrated Low Battery Comparator external Schottky diode is required and the system efficiency is improved. The current through the switch • Micro-Small 10-Pin MSOP or 3 mm x 3 mm QFN is limited to a maximum value of 1300 mA. The Package converter can be disabled to minimize battery drain. • EVM Available (TPS6101xEVM-157) During shutdown, the load is completely isolated from the battery. 2 Applications An autodischarge function allows discharging the • All Single- or Dual-Cell Battery Operated Products output capacitor during shutdown mode. This is especially useful when a microcontroller or memory is – Internet Audio Players supplied, where residual voltage across the output – Pager capacitor can cause malfunction of the applications. – Portable Medical Diagnostic Equipment When programming the ADEN-pin, the autodischarge – Remote Control function can be disabled. A low-EMI mode is implemented to reduce interference and radiated – Wireless Headsets electromagnetic energy when the converter enters the discontinuous conduction mode. The device is Simplified Application Circuit packaged in the micro-small space saving 10-pin MSOP package. The TPS61010 is also available in a 3 mm x 3 mm 10-pin QFN package.
