  • Forum Post: Re: TPS61016 with Lithium Iron Disulfide (1.8V) cells?

    Michael Day
    I can not recommend using the TPS61010 with an input voltage greater than 3.6V. I am not familiar with the new battery technology.

  • Forum Post: TPS62050 Step-Down, Vin vs. Vo

    Steve P. (NY)
    Looking for clarification on subject '800mA Synchronus Step-down Converter'. I'm assuming, given that this is a switching DC/DC regulator, that (generally) the input voltage can fall below the output voltage; this would not be the case with a linear regulator. Sh.3 of the data sheet...

  • Forum Post: Re: TPS63031 Voltage difference between Power- and Control-Stage

    Michael Day
    The TPS63030 VIN and VINA pins can be shorted together externally. A better option is to allow VINA to be powered through VIN through the internal resistor designed to connect these two pins. You need an additional filter capacitor with this method. This provides a cleaner voltage rail to power the TPS63030...

    Generally, we recommend you follow the design procedure in the datasheet and your schematic and layout match that of the EVM. See my comments below: Shlomi Yehezkia Q1: Can the PS/SYNC pin (power safe mode) be active for good? [D.A.] PS/SYNC is an input to enable power save mode or for a system...

    Q: TPS63020 by 1013270 , Please find the following question regarding the GND and power ground of the TP63020 and bq24020. The charger bq24020 powers up (VIN) the SPS TP63020. Can the charger ground be the same plan as the SPS GND pin 2. In all hoe should the ground separation between the two IC...

  • Wiki Page: TPS63020 VINA Pin Connection

    Daniel Acevedo
    Q: TPS63020 by 1013270 Should the VINA pin be also connected to VIN or is it internal connected? A: Re: TPS63020 by 1129650 VINA should be connected to a 0.1uF ceramic capacitor. VINA has an internal connection to VIN and does not need to be externally connected to VIN if the 0.1uF capacitor...

  • Wiki Page: TPS60151 - operate below 2.7V?

    Chris Glaser
    Original Question: Although this device is specified to operate with Vin between 2.7V and 5.5V, what happens as Vin drops below 2.7 to as low as 2.5V? I am looking for a 5V charge pump to recommend to a customer for providing the 5V bias to the TPS51216 DDR regulator, but Vin may drop as low as 2...

    Original Question: PVIN and AVIN Pin in TPS621x0 Hi, on the datasheet of the TPS62130 /40/50 is written that PVIN and AVIN need to be connected together. Is it the only way to operate? What happens if I connect two different voltages (like in other regulators) in order to save energy ? (e.g. PVIN...
