  • Forum Post: Re: Problem powering OMAP-L137 with a TPS650532

    Chris Glaser
    One good thing to try would be testing the power (TPS650532) without the processor. An easy way to do this is order the TPS65053 EVM and then test it with your components/values.

    Chris Glaser
    I split this thread as this is a new question. Can you post a schematic? What are your circuit connections--where is Vin connected, where are you measuring Vout, is there a load?

    Hello Sudarshan, What is the input supply of DCDC1? Can you please check VIN_DCDC1 , VOUT_DCDC1 and SW node of DCDC1 with a scope. In case you measure a short between the SW node of DCDC1 and GND, the internal FET is damaged. This could be due to voltage spikes on the SW node exceeding the...

  • Forum Post: Re: TPS65023 DC and LDO output max capacitance load

    Daniel Acevedo
    Jerel, There is no upper limit on the input capacitors. Any deviation from typical capacitor values on the output will have to be evaluated in terms of frequency response. The DCDC converters and LDOs are internally compensated for the capacitance in the datasheet. You could increase the capacitance...

    There are numerous reference designs on TI's processor power page ( ti.com/processorpower ). The following app note and the TPS60570 datasheet contain a reference design for the OMAP-L138. Powering Freon with TPS65070: http://focus.ti.com/lit/an/slva371a/slva371a.pdf TPS65070 Datasheet ...

  • Forum Post: TPS65053 - pull down when disabled?

    Andrea Ramos
    Hi, Can you please help answer the following question regarding the TPS65053: When the switching converters are disabled, is there any sort of active pull down resistor? The datasheet address the LDO's, but not the other outputs: “If disabled, the outputs of the LDOs are pulled...

  • Forum Post: TPS65053 question. Can I boost the VCC(3.6V) to 4.5V then connect to VINDCDC1/2.

    henry-liu
    A application like this: The battery (3.3V--4.2V) connect to TPS65053 VCC, and a DCDC converter boost the battery voltage to 4.5V, then 4.5V connect to VINDCDC1/2. But the VCC pin discription is--- Power supply for digital and analog circuitry of DCDC1, DCDC2 and LDOs. This pin must be connected...

  • Forum Post: RE: TPS65053 question. Can I boost the VCC(3.6V) to 4.5V then connect to VINDCDC1/2.

    Michael Green
    Henry, Yes, Vcc is the supply for the digital and the analog circuitry of DCDC1 and DCDC2 therefore, in order for the internal DCDC circuits to operate properly Vcc and Vindcdc must be the same voltage. Connecting them to the same power supply is also, needed.

  • Forum Post: TPS65053 Input Voltages and Sequence

    Scott Burton
    Hi Forum, I have a potential application for the TPS65053 in which I would want to have the 1A switcher sourced from 5V, but LDO1 and LDO2 sourced from 3.3V. With this in mind I have the following questions: 1/ Would you please confirm that I can connect VIN_LDO1 and VIN_LDO2/3 to 3.3V with VINDCDC1...
