Description

The TPS6113x devices provide a complete power supply solution for products powered by either a one-cell Li-Ion or Li-Polymer, or two- to four-cell Alkaline, NiCd, or NiMH batteries. The devices can generate two regulated output voltages. It provides a simple and efficient buck-boost solution for generating 3.3 V out of an input voltage that can be both higher and lower than the output voltage. The converter provides a maximum output current of at least 300 mA with supply voltages down to 1.8 V. The implemented SEPIC converter is based on a fixed frequency, pulse-width-modulation (PWM) controller using a synchronous rectifier to obtain maximum efficiency. The maximum peak current in the SEPIC switch is limited to a value of 1600 mA.
