Buck-boost, inverting & split-rail converters (integrated switch) – Tools & software
Featured reference designs
Isolated power supply is important for analog components like analog to digital converters (ADC) and operational amplifiers (Op-Amp) in the field of factory automation and control.
Since the use of high fidelity headphones is a growing trend for portable audio playback, higher performance DAC and Headphone Amplifiers are demanded.
Differential Headphone amplifiers require positive and negative voltages. In this reference design, both voltages are generated from a single input voltage with an all integrated split-rail converter.
This reference design describes a backup power circuit which addresses instantaneous protection against power interruptions by using a buck-boost converter and two stacked supercapacitors.
This reference design includes a complete power management solution for a standalone emergency call (eCall) system in an automotive environment.
Featured evaluation modules
The TPS65132 is designed to support positive / negative output voltage, for example to drive TFT-LCD panels up to 10” at least (from SFF to MFF like tablets). In this application the two output rails are usually connected to the Source Driver IC.
The TPS65130EVM-063 is an evaluation tool for the TPS65130 Positive and Negative Output DC-DC Converter for general-purpose split-rail supplies, industrial applications and LCD or OLED displays.
The TPS63025xEVM-553 enables test and evaluation of the Texas Instruments’ TPS63025 device family, a 2.5MHz (typ.) fully integrated buck-boost converter.
