TPS61030RSAR

The TPS61030RSAR is a synchronous Boost Converter with 4A switch. The TPS6103x device provides a power supply solution for products powered by either one-cell Li-ion or Li-polymer or a two to three-cell alkaline, NiCd or NiMH battery. The converter generates a stable output voltage that is either adjusted by an external resistor divider or fixed internally on the chip. It provides high efficient power conversion and is capable of delivering output current up to 1A at 5V at a supply voltage down to 1.8V. The implemented boost converter is based on a fixed frequency, pulse-width- modulation (PWM) controller using a synchronous rectifier to obtain maximum efficiency. At low load currents the converter enters power save mode to maintain a high efficiency over a wide load current range. The power save mode can be disabled, forcing the converter to operate at a fixed switching frequency. It can also operate synchronized to an external clock signal that is applied to the SYNC pin.
