Part Number: TPS61390 Other Parts Discussed in Thread: ACF2101
The TPS61390 has built in current mirrors. You can select between two current mirrors, sample the voltage at a resistor connected to the mirror at a moment in time, and read back this voltage…
Hi Charles,
1. Current mirror output pins: please refer to this app notes for detail, How to Sample the Small APD Current Precisely With the TPS61390 Boost Converter . If output current cannot be measured precisely, this current mirror pins can used to measure…
Part Number: TPS61390 Other Parts Discussed in Thread: TPS61391 Hi team, Good day.
What is the proper configuration of the TPS61390 if the current mirror will not be used? Can we float the Avcc pin and short the monitor pins to ground?
Regards, Carlo
Part Number: TPS61390 Hi team,
Good day. Our customer is using the TPS61390 and they would like to have a 60V output using a 3V power source. However, upon testing their design, 60V is achieved at 3.2V supply only. Please refer to the schematic below…
Part Number: TPS61390 Other Parts Discussed in Thread: TPS61391 , TEST
Hi,
My customer considers using the TPS61390 as mic phantom power.
Can this device output 12mA on VIN=5V, VOUT=48V?
I inquiry because the output current is drawn by the only 10mA in…
Part Number: TPS61390 Hi team,
I saw there is a Rprotect to MONIN in typical application circuit. What is the recommended value for this R? Or, how to decide its value?
Thanks.
Part Number: TPS61390 I want to use TPS61390 to ouput 56V DC voltage. Is there some reference circuit which can use to accomplish my requirement?
Thanks for the answers.
Part Number: TPS61390 Other Parts Discussed in Thread: TPS61391 Hello,
My customer plans to use TPS61390.
But he does not use VSP pin, instead he would like to translate MON1/MON2 pin current to voltage using a trans impedance amp and monitor the output…
Part Number: TPS61390 Other Parts Discussed in Thread: ABS We'd like to max out the 61390 and get an 85 volt output from a 2.8 to 3.9 volt input in order to drive an ultrasonic transducer. Will this work and what needs to be done to set current through…
Part Number: TPS61390 Dear TI Team,
It's possible to obtain a variable Vout with this chip, maybe controlling the FB voltage?
I need to have a boost converter with variable Vin (1.8-5V) and variable Vout (15-60V) with Imax out = 10mA.
Thank you in…
