The devices provide an output current of 200 mA with a supply · Start-Up Into Full Load With Supply Voltages voltage of only 0.9 V. The converter starts up into a as Low as 0.9 V, Operating Down to 0.8 V full load with a supply voltage of only 0.9 V and stays · 200-mA Output Current From 0.9-V Supply in operation with supply voltages down to 0.8 V. · Powersave-Mode for Improved Efficiency at The converter is based on a fixed frequency, current Low Output Currents mode, pulse-width-modulation (PWM) controller that · Autodischarge Allows to Discharge Output goes automatically into power save mode at light Capacitor During Shutdown load. It uses a built-in synchronous rectifier, so, no external Schottky diode is required and the system · Device Quiescent Current Less Than 50 mA efficiency is improved. The current through the switch · Ease-of-Use Through Isolation of Load From is limited to a maximum value of 1300 mA. The Battery During Shutdown of Converter converter can be disabled to minimize battery drain. During shutdown, the load is completely isolated from · Integrated Antiringing Switch Across Inductor the battery. · Integrated Low Battery Comparator An autodischarge function allows discharging the · Micro-Small 10-Pin MSOP or 3 mm x 3 mm output capacitor during shutdown mode. This is QFN Package especially useful when a microcontroller or memory is · EVM Available (TPS6101xEVM-157) supplied, where residual voltage across the output capacitor can cause malfunction of the applications. When programming the ADEN-pin, the autodischarge function can be disabled. A low-EMI mode is im- · All Single- or Dual-Cell Battery Operated Prod- plemented to reduce interference and radiated elecucts Like Internet Audio Players, Pager, Port- tromagnetic energy when the converter enters the able Medical Diagnostic Equipment, Remote discontinuous conduction mode. The device is pack- Control, Wireless Headsets aged 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. The TPS6101x devices are boost converters intended for systems that are typically operated from a singleor dual-cell nickel-cadmium (NiCd), nickel-metal hydride (NiMH), or alkaline battery. Please |
