DESCRIPTION
The TPS6113x devices provide a complete power supply solution for products powered by either a one-cell Li-Ion or Li-Polymer or a two up to four-cell Alkaline, NiCd or NiMH batteries. The device can generate two regulated output voltages that are either adjusted by an external resistor divider or fixed internally on the chip. It also provides a simple and efficient buck-boost solution for generating 3.3 V out of a one-cell Li-Ion or Li-Polymer battery at 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. The converter can be disabled to minimize battery drain. During shutdown, the load is completely disconnected from the battery. A low-EMI mode is implemented to reduce ringing and in effect lower radiated electromagnetic energy when the converter enters the discontinuous conduction mode. A power good output at the SEPIC stage provides additional control of any connected circuits like cascaded power supply stages or microprocessors. The built-in LDO can be used for a second output voltage derived either from the SEPIC output or directly from the battery. The output voltage of this LDO can be programmed by an external resistor divider or is fixed internally on the chip. The LDO can be enabled separately i.e., using the power good of the SEPIC stage. The device is packaged in a 16-pin QFN 4 x 4 mm (16RSA) or in a 16-pin TSSOP (16 PW) package.
