Part Number: LMR62421 Hello Zack, We have done with LMR62421 placements. Please check the placements of a LMR62421 IC Placement.. Please tell, this placement is correct?
Part Number: LMR62421 Other Parts Discussed in Thread: LMR64010 , I am using LMR62421XMF/NO regulator to boost from Li ion battery 3.7 V to 12V . I had checked the switching output but no pulsing i can see .
Also i am cascading two boost regulator …
Part Number: LMR62421 Other Parts Discussed in Thread: LM2735 Hi,
I am seeing 3.3V on the output of the LMR62421 with the enable is low. The voltage seems to be a diode drop value of the input voltage so I am not sure what is going on. I have attached…
Part Number: LMR62421 We used LMR62421 SOT package to drive 4 LED with Vf 6v @ 50mA. Somehow, LMR output voltage drops to 6.4v. LMR is configured for 7.5v output. Is there any limitations. we used 10uF output cap. we also tried 22uF and 470uF output cap…
Part Number: LMR62421 Other Parts Discussed in Thread: TPS61033 , , TPS61022 , TPS61288 I want to know that the IC claims that it can deliver upto 2.1 AMPS of current ,can anyone please let me know the input and output for that?
my second question…
Hi Muhammad,
Thanks of reaching out with your questions and for using the LMR62421.
I have contacted the engineer supporting this device and he should respond shortly.
Thnaks,
Garrett
Part Number: LMR62421 Dear TI: My customer would like to know whether LMR62421 will have a sudden increase in output under certain conditions.Such as normal output 9V, abnormal output peak pulse voltage 12V. Do output anomalies occur when the input voltage…
Part Number: LMR62421 Hi, I have the following design using the LMR62421 to boost a 4.5V input to a 12V output, with a nominal load of ~100mA, and a damped LC low-pass filter on the output: As-is, the output only approaches 12V measuring an open circuit…
Part Number: LMR62421 Other Parts Discussed in Thread: LAUNCHXL-F28379D Hi TI, I wanted to know what current the boost converter that is in the launchpad XL F28379D delivers to the output, which is formed by an LMR62421 regulator that converts from 3…
Part Number: LMR62421 I am using LMR62421 as a boost regulator, Vin from 3.1V to 4.2V, Vout 12.0, 200mA. I have assembled 5 prototypes non were working up to place a 100K Ohm resistor in series with enable pin.(pin4).
The datasheet does not mention…
