Part Number: TPS82140 I put together a 5vdc in, 1.2vdc out power supply using the circuit produced by TI Power Designer (minus the PG output), but it cannot supply anywhere close to the rated current output. The rated output is 2a but at 1a load, the…
Other Parts Discussed in Thread: TPS62913 , TPS62912 Hi team,
We are using TPS and TPSM integrated inductor modules on the FPGA side(an RF product).some rails are taking low current, its switching frequency is low(below1Mhz). Do we need to add a second…
Part Number: TPS82140 Hi Team,
My customer just finished art work of their new board mounted 5pcs TPS82140.
Could you review their schematic and layout quickly and point out if there is not good point in it.
You can find the files from here(internal link…
Part Number: TPS82140 I am using the TPS82140SILT as a 3.3V regulator from 12V input. The 3.3V is powering a MCU that I need to use for power down sequencing of a class D amp. Can I have a 1200UF output capacitance on the TPS82140SILT to keep the system…
Part Number: TPS82140 Other Parts Discussed in Thread: TPS62140 Hello,
The TPS82140 has an upper switch current limit of 4A (range 3-4A) - if the output is shorted to GND, would the module essentially hiccup to 4A at some frequency, with Thermal protection…
Part Number: TPS82140 The data sheet states that R2 should not exceed 100 kohm for high efficiency. What is the recommended value for R2? VOUT = 1.2V is planned.
Part Number: TPS82140 Hello team,
I use TPS82140 for 12V - 1.8V conversion.
I observe TPS82140 output voltage rises up to 2.0V approximately 50ms after the start-up.
Could you please help me to address this issue?
Please find the schematic and wavefo…
Part Number: TPS82140 Other Parts Discussed in Thread: TPS82150 , I investigating about the reason of damage for a few TPS82140 and TPS82150.
Customer condition is below;
・Schematic is based on EVM with adjustment Rfb.
・Vout have many case: 1.2V~5V, these…
Part Number: TPS82140 Hello,
Regarding VOUT pins 4 and 5. Can we assume they're tied together internally, or do they have to be tied together on the PCB?
