The converter output voltage can be adjusted from 1.5 V to a maximum of 3.3 V, by an external resistor divider or, is fixed internally on the chip. The devices provide an output current of 200 mA with a supply voltage of only 0.9 V. The converter starts up into a full load with a supply voltage of only 0.9 V and stays in operation with supply voltages down to 0.8 V. The converter is based on a fixed frequency, current mode, pulse-width-modulation (PWM) controller that goes automatically into power save mode at light load. It uses a built-in synchronous rectifier, so, no external Schottky diode is required and the system efficiency is improved. The current through the switch is limited to a maximum value of 1300 mA. The converter can be disabled to minimize battery drain. During shutdown, the load is completely isolated from the battery. An autodischarge function allows discharging the output capacitor during shutdown mode. This is especially useful when a microcontroller or memory is 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 implemented to reduce interference and radiated electromagnetic energy when the converter enters the discontinuous conduction mode. The device is 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.
