TMS570LS3137: LS3137 can use TPS65381 for VCC supply or not?

Huihuang Chen

Part Number: TMS570LS3137

For TPS65381 the VDD1 maximum output current is 600mA, but the LS3137 VCC in LBIST or PBIST mode maximum VCC current is 700mA,

So that means TPS65381 not suitable for LS3137?

Any other suitable PMIIC can working with LS3137?

Hello Huihuang,

If the maximum output of TPS65381 doesn't meet the power supply requirement, you need to use another 1.2V power suppy for TMS570, and also use TMS65381 for 1.2V monitoring.
