Part Number: LM26480 Other Parts Discussed in Thread: TPS65050 Tool/software: Hi, I need a Power Management IC with 4 LDO's in it. The requirements are
1. Each LDO should have individual EN pins
2. Each LDO output should be hardware configurable.…
Part Number: LM26480 Tool/software: Request for PMIC Recommendation with Specific Features
Dear Texas Instruments Support Team,
We are looking for a power management IC (PMIC) that meets the following specifications for our application:
Battery…
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,

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…
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 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…
Part Number: LM26480 Hi,
The Case we used is as follows:
SW1: 0.9V/135mA
SW2: 1.8V/150mA
1.How long is Start-Up to ready in these two cases?
2.Does Turnon time indicate the position of the arrow as shown below?
Thank you
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
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. …
