Because of the Thanksgiving holiday in the U.S., TI E2E™ design support forum responses may be delayed from November 25 through December 2. Thank you for your patience.
Hi David,
The regulators are optimized for an inductor value of 0.5uH so it's not surprising that lowering the inductance to 1uH helped the performance. However, the LM26484 datasheet shows that for Vout >= 2V, a 2.2uH inductor is recommended.

Part Number: LM26484 Other Parts Discussed in Thread: TPS65023 , TPS650250 , LM26480 , LM3881 Hi,
I'm looking at LM26484 with the potential to serve as a PMIC to power up a WiFi module. However what I noticed was that module has its own power sequence required…
Part Number: LM26484 Other Parts Discussed in Thread: LM26480 Hi,
I want to use LM26484 in new design.
I need to know is there possibility to achive 1.8V as LDO output voltage, with AVDD = AVIN = PVIN = 3.3V conditions?
In DS there is only information…
Part Number: LM26484 Hi Team,
LM26484.docx Please help with the below problem.
TI support is required as I in pre-production phase.
I have a problem with 3.3V supply on my boards:
(1) Burnt on 2 boards
(2) On working board we see ~0.5V ripple (182820.jpg…
Part Number: LM26484 Dear TI Support,
According to the LM26484 datasheet, it recommends LPS4012–222MLB as an output inductor for Vout>2.0V.
(1) Why not LPS4414–222MLB? (same footprint as LPS4414–504MLB recommended for lower voltages)…
Part Number: LM26484 Hi team,
My customer is designing a proto type with using LM26484 now.
I have a question about a case that he doesn't use the function of internal LDO(ENLDO=Low). I understand that the voltage of LDOGATE pin will be low regardless…
Other Parts Discussed in Thread: OMAPL138 , LM26484 We are using LM26484 in our board, based on OMAPL138. The system is going right now in production, after two prototype runs. So LM26848’s connections, passive components and PCB layout has been well revised…
Other Parts Discussed in Thread: LM26484 I'm using an LM26484 dual switcher + LDO controller in a design that does not use the LDO controller. Is it okay to leave the LDOGATE and LDOFB pins unconnected (floating)? Even if the ENLDO is tied high? This…
Other Parts Discussed in Thread: LM26484 , LM26480 HI
My customer would like to evaluate this IC for their design, but i understand that there is no EVB to support.
I would like to check if there is any recommended way to evaluate LM26484 for quick verification…
Other Parts Discussed in Thread: LM26484 I am not able to find in LM26484 data sheet, if shoud I meet a maximum rise time (or fall time) for ENSW1, ENSW2 and ENLDO signals. If no limit exists, I could use a simple RC circuit to delay enable from power…
