Texas Instruments TPS61251 and TPS61252 boost converters provide a power supply solution for products powered by either a three-cell alkaline (NiCd or NiMH) battery or a one-cell Li-Ion or Li-polymer battery. The wide input voltage range of the TI TPS61251 and TPS61252 are ideal to power portable applications like mobile phones, computer peripherals, solid state drives, and wireless modems. TI TPS61251 boost converters feature adjustable constant current and a snooze mode that draws only 2µA (typical). TI TPS61252 boost converters offer adjustable input current limit. These TI devices are programmable from 100mA up to 1500mA.
