Product Summary

The TPS62110RSAT is a low-noise synchronous step-down dc-dc converter that is ideally suited for systems powered from a 2-cell Li-ion battery or from a 12-V or 15-V rail. The TPS62110RSAT is a synchronous PWM converter with integrated N- and P-channel power MOSFET switches. Synchronous rectification is used to increase efficiency and to reduce external component count. To achieve highest efficiency over a wide load-current range, the TPS62110RSAT enters a power-saving, pulse-frequency modulation (PFM) mode at light load currents. Operating frequency typically 1 MHz, allowing the use of small inductor and capacitor values. The applications of TPS62110RSAT include Point-of-Load Regulation From 12-V Bus, Organizers, PDAs, and Handheld PCs, Handheld Scanners.
