Part Number: LM26480 Tool/software: Hello,
I'm trying to reach the part owner for the LM26480 and request a call about this part, please.
thank you,
Stan
Part Number: LM26480 Hello, I have a question about the input capacitor requirements for the buck regulators of the LM26480. The minimum capacitance is 10uF as given in section 7.7 of the datasheet. The application circuit in Figure 26 uses 10uF capacitors…
Part Number: LM26480 Dear TI team,
Good evening.
We have designed LM26480 according TI reference and webench design for FPGA power supplies.
As I said we have connected Buck and LDO outputs from LM26480 to FPGA.
We have given delay between two LDO outputs…
Part Number: LM26480 hi,
With LM26480, my customer had set its buck 1 output at 3.3V@500mA. 3.3v is out of (Buck1 : 0.8 V to 2 V at 1.5 A) that the recommended range of buck 1 listed in LM26480 datasheet . is there any risk?
customer schematic is attached…
Part Number: LM26480
Yes; a set of RC (Resistor and Capacitor) values were used on TI LM26480 EVM with VCC=3.3V on 3 "EN" pins (ENSW2, ENLDO1, ENLDO2) to control the power up delay for the sequence. ENSW1 connects to VCC directly without RC delay…
Part Number: LM26480-Q1 Hello,
I am currently designing power circuitry using LM26480-Q1 and I have question regarding the GND separation for this chip.
As this chip has pin for core ground (GND_C) , LDO ground (GND_L) , and switching GND (GND_SW1, GND_SW2…
Part Number: LM26480 Is there a reason why even before the Enable pins are asserted for both of the bucks, nPOR is high? I.e. Why is nPOR high before t0?
Part Number: LM26480 Hi Team,
Our customer designed an application using LM26480SQ-AA, however, he would like to know if he can replace it with LM26480SQ-CF. I understand that the difference between the two is that LM26480SQ-AA buck mode is auto-mode and…
Part Number: LM26480 Do we need an RC to make sure the delay is happening? I saw another post where they recommend a 1uF cap but I don't think the trace resistance will be high enough to achieve 8ms delay.
Part Number: LM26480 We have a use case for LM26480 where SW1 will supply ~0.5A, but SW2 must now supply 1.8A due to a recent design change.
1.8A is more than the 1.5A recommended rating of the device, but the peak ripple current is still less than the…
