The TPS6030x is a high-efficiency charge pump that converts a single-cell voltage to 3.0V/3.3V. It features a regulated 3V or 3.3V output voltage with up to 20mA output current. It is optimized for 1.2V battery voltage and achieves up to 90% power conversion efficiency. The product does not require an inductor and only needs five small 1uF ceramic capacitors to build a complete high-efficiency DC/DC charge pump converter.
The TPS60300, TPS60301, TPS60302, and TPS60303 are step-up, regulated charge pump devices designed for space-critical battery-powered applications. They generate a regulated 3-V or 3.3-V output voltage from a single-cell input ranging from 0.9 V to 1.8 V (suitable for alkaline, NiCd, or NiMH batteries). The device operates in LinSkip mode, seamlessly switching between pulse-skip and constant-frequency linear-regulation modes to maintain high power conversion efficiency up to 90%.
