Part Number: TPS65261-1 Hi Expert,
My customer found the issue about Lx pin negative voltage ringing. (minimum around -2V)
Zoom-in
Absolute max of Lx pin : -1V to 20V
This waveform is reached negative side(-2V)
Is it any problem?
Also, Datasheet is…

Customer finds the device TPS65261-1 works normal at 25℃, but the output start to jitter when IC works at -10 to -40℃. Then we tested the control loop, found the curve…
Part Number: TPS65261-1 Other Parts Discussed in Thread: TPS54335A Hello,
I am considering the circuit below. The PGOOD signal of TPS65261-1 controls two TPS54335A. EN of TPS54335A is set to turn on when VIN is 9V. The reason is to start TPS54335A after…
Part Number: TPS65261-1 Hello,
I would like to ask you about the timing of V7V output in Automatic Power Sequencing. V7V is output when ENx becomes "H". However, in Fig. 29, ENx is "H" before VIN. In this case, at what timing is V7V output…
Part Number: TPS65261-1 Hello,
I would like to ask you about the timing of EN1 and EN2 of Automatic Power Sequencing. In the data sheet Figure 29, first of all, EN1 and EN2 are "H". Is it necessary to set EN1 and EN2 to "H" before VIN starts up…
Part Number: TPS65261-1 Hi team,
My customer is going to use 1ch and 2ch of TPS65261-1. Could you tell me the handling of the unused channel? In this case, channel 3.
Are the following connections correct?
PVIN3 : Floating or PGND
PGND3 : PGND
LX3 : F…
Part Number: TPS65261-1 Hello,
I would like to ask you about TPS65261-1. In the item of data sheet 8.3.1, the recommended resistance values when the output voltage is 5V are R1: 73.2kΩ and R2: 10kΩ. However, I plan to use a resistor with an…
