Description

The 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 of TPS6101x 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 200mA 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 of TPS6101x 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 of TPS6101x can be disabled to minimize battery drain. During shutdown,the load is completely isolated from the battery.
