This reference design uses the TPS61088 to provide an envelope tracking power supply circuit for an audio power amplifier (PA). By adding the audio envelope signal to the FB pin, the output voltage of the TPS61088 can be varied according to the envelope of the audio signal. Therefore TPS61088 can provide dynamically changing power supply voltage to the PA. As a result, the PA maintains high efficiency over the entire output power range.

This reference design demonstrates how to implement a capacitive touch button, commonly used as a setting button in a proximity switch, in an ultra-small 3.5mm wide PCB based on TI's CapTIvate™ technology. When combined with the highly integrated IO-Link PHY, flexible PNP or NPN outputs are possible. The SIO stage provides reverse polarity, ESD, EFT and surge protection, making the design compliant with IEC 61000-4 standards. Hall sensors with analog output signals enable flexible use by teaching the distance to magnetic objects via a capacitive teach button. This analog signal is captured by the MCU's integrated ADC.
The MAX17559 is a dual-output, synchronous step-down controller that drives nMOSFETs. The device uses a constant- frequency, peak-current-mode architecture. The two outputs can be configured as independent voltage rails. Input capacitor size is minimized by running the two outputs 180° out of phase. The IC supports current sensing using either an external current-sense resistor for accuracy or an inductor DCR for improved system efficiency. Current foldback or latch-off limits MOSFET power dissipation under short-circuit conditions. The IC provides independent adjustable soft-starts/stops for each output and can start up monotonically into a pre-biased output. The IC can be configured in either PWM or DCM modes of operation, depending on whether constant-frequency operation or light-load efficiency is desired. The IC operates over the -40°C to +125°C temperature range and is available in a lead(Pb)-free, 7mm x 7mm, 32-pin TQFP, package.
