TPS60125PWP

Product Summary

The TPS60125PWP step-up, regulated charge pump generates a 3.3-V or 3-V ±4% output voltage from a 1.8-V to 3.6-V input voltage two alkaline, NiCd, or NiMH batteries). The TPS60125PWP can deliver an output current of at least 200 mA from a 2-V input. The TPS60125PWP features the power-saving pulse-skip mode to extend battery life at light loads. The TPS60125PWP features a power-good output. The logic shutdown function reduces the supply current to a maximum of 1 μA and disconnects the load from the input. The TPS60125PWP is available in the small, thermally enhanced 20-pin PowerPAD package (PWP). The applications of TPS60125PWP are: (1)Applications Powered by Two Battery Cells; (2)Portable Instruments; (3)Battery-Powered Microprocessor Systems; (4)Miniature Equipment; (5)Backup-Battery Boost Converters; (6)PDAs, Organizers, Laptops; (7)MP-3 Portable Audio Players; (8)Handheld Instrumentation; (9)Medical Instruments (e.g., Glucose Meters); (10)Cordless Phones.
