TPS65132S: Iq test condition about the TPS65132s

Part Number: TPS65132S
Other Parts Discussed in Thread: TPS65132

Dear TI,

We found the Iq value in TPS65132's datasheet. The typical value is 0.54mA.

1) Can you help clarify the test condition of this Iq value? Are the outputs(Vpos and Vneg) enabled or disabled?

2) If it is tested when Vpos and Vneg exist, then what's the Maxmin value besides the typical value offered?

3)If it is tested when outputs are disabled, then what's the value when outputs are enabled?

Thanks for help.

    Hello,

    1) The parameter, as specified in the datasheet, is with device enabled but not switching i.e. outputs are not regulated to the set voltage.

    2) As specified in 1 above, VPOS/VNEG are not regulated.

    3) With outputs enabled and regulated but not loaded, current from input supply is dependent on the input supply value itself and the set output voltage. For example, with VIN=3.4, VPOS=5.4V, VNEG=-5.4, current from input supply is typically ~1.1mA.

    Kind Regards,

    Liaqat
