TPS61259 - 3.5-MHz High Efficiency Step-Up Converter

Download the TPS61259 datasheet PDF. This datasheet also covers the TPS61253 variant, as both devices belong to the same 3.5-mhz high efficiency step-up converter family and are provided as variant models within a single manufacturer datasheet.

Description

The TPS6125x device provides a power supply solution for battery-powered portable applications.

Intended for low-power applications, the TPS6125x supports up to 800-mA load current from a battery discharged as low as 2.65V and allows the use of low cost chip inductor and capacitors.
