TPS650330-Q1: BOOSTXL-TPS65033 failed to connect to device TPS650330

Part Number: TPS650330-Q1
Other Parts Discussed in Thread: BOOSTXL-TPS65033, MSP430F5529

Hi Team,

When I connect BOOSTXL-TPS65033 to PC via MSP430F5529 LaunchPad. The on board LED D1 doesn't light up even SW S2 set to active position.

I measure the voltage output from U2, it is zero voltage. It looks U2 is malfunction.

Can I have the schematic of BOOSTXL-TPS65033 EVM for troubleshooting?




  • Hi Calvin,

    S2 drives the enable for the U2 load switch. Have you confirmed that 3.3 V is present at the U2 input (capacitor C5)? 

    Since this device is not yet released, please accept my E2E friend request, and I can send the schematics via private message.
