Blake, Given the unique set of requirements I don't think we have any PMICs which will cover everything you need. The TPS65311-Q1 looks like a decent fit, but it doesn't appear to have separate enable lines for each rail. I think your best bet…
Part Number: TPS65251 Hi,
My input voltage is 12V, O/p of buck1 = 3.3V, Buck2 = 2.5V, Buck3 = 1.8V.
1. During the bringup, the EN of Buck1 is toggling i have checked the input ripple which is around 500mV.
2. When i am checking the datasheet there where…
Hi, Gabriel 1. The IC has the discharge time enable pins(tD) function. (see the page7 of datasheet.) It can assure the EN cap fully discharged. The TPS65251-1 is similar with TPS65250, they have same IP. In the page13 of TPS65251-1, there is time…
Part Number: TPS65251 Hello,
I have a question about thermal performance for the TPS65251.
We have measured spur performance at the output 1 of the TPS65251 eval. board. Input voltage was 10.2V, output voltage was set to 6.2V. Output current 1.59A (3.9Ohm…
Part Number: TPS65251 Hi, Team
My communication customer is using TPS65251-3 in their small cell products. They find the output voltage will drop during startup, if the outpu voltage is set to > 3.5V.
Here is customer schematic. The CH3 of TPS65251…
Part Number: TPS65251 Hello Team,
may I ask you for the accuracy of the internal reference over the whole temperature range (Vin = 12V), please?
The data sheet only specifies the accuracy of the feedback voltage at Vin = 12V, Tj = 25°C with 0.8V +/- 1…

Part Number: TPS65251 Hi,
I have a issue about TPS65251 output ripple over 200mV when light load,
when buck 1 (Vout =3.3V) in light load, ripple peak to peak about 271mV, max. 3.64V, min. 3.4V,
is it expected? in our design LOW_P always pull down to GND…
