TPS61010 具有可调节输出的低输入电压同步升压转换器
TPS61010 描述
e TPS6101x devices are boost converters intended for systems that are typically operated from a single- or dual-cell nickel-cadmium (NiCd), nickel-metal hydride (NiMH), or alkaline battery.
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
