Part Number: LM5149 Hi Sir,
My customer use dual LM5149 at their system and please check schematic as attached. In their field test, both of the LM5149 will be failed when 56V power adaptor is plugged. VCC and VDDA pin short to GND. Would you please helping…
Part Number: LM5149 We are designing a (48 to 13.8) V dc-dc for a 500 W dc-dc.
Planning to make 2 phase interleaving using LM5149.
Can we use LMG2100 GaN fet as half bridge module for interfacing with LM5149
Part Number: LM5149-Q1EVM-400 Hi Texas Instruments team,
We are currently customizing the evaluation board (LM5149-Q1EVM-400) for 12V and 20A output configuration. Basically, we are de-populating some components and populating other components which sets…
Part Number: LM5149 I want to know the operating current of LM5149
My Operating is as mention below
Input Voltage 30 - 50V
Output Voltage - 28V, 5A
Problem is when i am using its internal regulator, it is generating heat due to wide voltage differenc…
Part Number: LM5149-Q1 Other Parts Discussed in Thread: LM5149 Hi team,
Could you please help share how the LM5149 20ns typ dead time is defined? Take LO off to HO on deadtime as example, is it counted from LO decreasing moment, or from LO dropping below…
Part Number: LM5149-Q1 Hi team,
My customer is using reverse protection diode before the Vin_emi pin, and has input cap before the diode. Does it also require this cap to have >100mohm ESR?
Part Number: LM5149-Q1EVM-400 Other Parts Discussed in Thread: LM5149 What is limiting the input voltage on this eval board to 72V (part is rated to 80V)? Noticed that C26 (on VIN) is only rated to 50V which is a problem even for 72V operation.
Part Number: LM5149 Hello Sir:
Please kindly help to check our schematic.
Our input range is 42V to 58.8V, and output power is 25V/3.5A.
Looking forward your feedback.
Thanks a lot.
Part Number: LM5149-Q1 Hi TI Team, We wanted to do the WEBENCH simulation for the part: LM5149-Q1 to understand its transient behaviors.
When I click the simulation option, it says: “simulate option is not yet enabled for this design.” Kindly…
Part Number: LM5149-Q1 Hi Teams,
I'm setting LM5149-Q1 Vout: 3.3V、Iout: 15A、 Ambient Temp: 85°C，when system Vin:40V to 3V to 40V，3V 10mS, rise time and fall time 0.1 mS
Q1: Output voltage figure
Q2: If have pulse how to avoid it
