Hi,
We are designing power supply for MSP430F247 - used in one of our Smart Energy Measurement applications. A single 12V 5A SMPS will power up the on-board TPS560200 to provide 3.3V 200mA output for MSP430F247& other board components. From the WEBENCH simulations, we observe 0.014V ripple on the TPS560200 output voltage. We are further smoothing this ripple out using 10uF & 100nF capacitors on each MSP430F247 supply pins. However, we still are worried whether the voltage ripples might interfere with the MSP430F247 operation.
Could someone please suggest if the above power supply configuration works good for MSP430F247? Please also let us know if there is a better way of approaching voltage ripples above. No RF components on board. MCU operating at 14MHz.
Regards,
Ravi
