Product Summary
The TPS62005DGSR is a low-noise synchronous step-down dc-dc converter. The TPS62005DGSR is ideally suited for systems powered from a 1-cell Li-ion battery or from a 2- to 3-cell NiCd, NiMH, or alkaline battery. The TPS62004DGSR operates typically down to an input voltage of 1.8 V, with a specified minimum input voltage of 2 V. The applications of the TPS62005DGSR include Low-Power CPUs and DSPs, Cellular Phones, Organizers, PDAs, and Handheld PCs, MP-3 Portable Audio Players, Digital Cameras, USB-Based DSL Modems and Other Network Interface Cards.
