Part Number: TPS61391 Hello Team,
A design requires a voltage of ±80V to power an amplifier. Looking at the TPS61391 datasheet and EVM, it seems this part will work.
If I'm using the EVM as reference and outputting ±80V, what's the maximum output…
Part Number: TPS61391 Hi there,
The datasheet mentions the "Quiescent current into VOUT pin". What do you mean by VOUT pin? From the IC pinout, I do not see any VOUT pin.
One more thing: "Choose RDOWN to be approximately 10 kΩ. Slightly increasing…
Part Number: TPS61391 Other Parts Discussed in Thread: TPS61376 , TPS61390 Does the spec for I_LIM_SW [800, 1000, 1200] mA mean that the TPS61391 internally limits the inductor current to 1000 mA (+/- 200), or that the application design must not exceed…
Part Number: TPS61391 Other Parts Discussed in Thread: TPS61390 , Hi,
TPS61391 has current mirror bias current spec in EC table like TPS61390. But it doesn't have any detailed description on MON1 & MON2 output current equation. Does the output current of…
Part Number: TPS61391 Hi together,
I have designed a PCB for supplying an APD. I used the TPS61391 (which can up the voltage to 85V) and then a charge pump to triple the voltage from the output IC since the APD can be supplied with a voltage up to 240V…

Part Number: TPS61391 Hi team!
I wanted to calculate inductor current when using TPS61391 Vin =3.3V, Vout =45V, L=4.5uH, Iload=10mA or 5mA. It worked in DCM, so I am not sure how to calculate it. Can you help to solve it?
Part Number: TPS61391 Hello, Datasheet 7.3.3 states the maximum voltage on MON1 and MON2 is 2.5V. What kind of issues could happen when each terminal voltage becomes 2.5V or more?
Is each terminal clipped to 2.5V and no more voltages? The current divider…
