TPS84259: TPS84259 schematic review

Chris Peng

Part Number: TPS84259

Hi BU friends,

Could you please help to review the schematic of TPS84259?

The VIN is 12V, and the Vout=-5V; customer told me that the output is just -0.794V, not the -5V.

Thanks and appreciate for your help.

Hello

Double check your component values. Be sure that the resistor connected to VADJ is not shorted or open.

Also, be sure that the load is not too heavy. Try to start-up with no load.

Please monitor the voltage on the phase pin(s) and show us what it looks like.

Thanks
