Page 8: Introduction
Chapter 1 Introduction The Texas Instruments TPS6030x charge pumps are regulated voltage converters intended for use with a single NiCd, NiMH, or alkaline cell. The TPS60300 and TPS60302 have an output voltage of 3.3 V from an input signal between 0.9 V and 1.8 V. The TPS60301 and TPS60303 have an output voltage of 3 V from an input voltage between 0.9 V and 1.8 V. -
Page 9: 1.1 Basic Operation Of The Device
1.1 Basic Operation of the Device The TPS6030x series are charge pumps working either in a tripler or in a quadrupler mode. They consist of an unregulated doubler stage with its capacitors C FLY1 . Its output voltage can be found at OUT1. The voltage at OUT1 is OUT1 internally connected to the input of a regulated charge pump that works in a ×1.5 or ×2 mode, respectively. -
