  • Wiki Page: TPS61241 : 　Pre-bias is applicable?

    Michael Day
    Q: TPS61241 : 　Pre-bias is applicable? by 569213 Can I apply pre-bias to the TPS61241 output through current limiting resister and diode from an LDO, while VIN equals to Zero voltage and is powered on/off keeping Enable to Low. Also, is the low side switch FET state on or off when TPS61241 is...

    In general, if there is pre-bias voltage on the output and no input voltage, the body diode of the high side MOSFET will conduct and allow the input voltage to be at one diode drop below the pre-bias. For 5 V pre-bias this may allow the TPS54325 to turn on. See (Please visit the site to view this file...

    Chris Glaser
    Q: Can the TPS6206x safely start into an output that is pre-biased to some voltage? Will it sink current from the output? A: Yes, these devices start normally into a pre-bias. Here is an example of the EVM (configured to give 1.8V out) starting into a 1V pre-bias: (Please visit the site to...

    Having a pre-bias on the output of the TPS63000 is not an issue. When enable is low, the TPS630xx internal circuitry is off and no current will flow in the reverse direction regardless of VIN presence.

    Bryan McLaughlin
    Original Question: TPS62090 and TPS62143 - Is 2V prebias okay? by Bryan McLaughlin For the TPS62090 , I understand there is about 200-ohm resistor to GND during disable. Is it safe for the device if the output will have a DC prebias of about 2V during the disable stage and upon enable stage when the...
