Dear Sir,

We are looking for an equivalent IC for part no: LT8609AEMSE#TRPBF.

It would be great if you suggest pin to pin compatible IC.

Hello Murthy,

Thanks for your interest in using a TI device. I do not have a pin-to-pin solution for this case, but the LMR33630 has the same functionality.
Can you provide further application requirements? Maybe I can find a better solution?

Regards,
Alejandro

Murthy,

See two options below:

LM60430
1. Smallest package option
2. Enhanced QFN package for excellent thermals
3. 36-V, 3-A rated
LM61440
1. 4-A current rating for more flexibility
2. Similar features set to LT8609

Alejandro

Hi Murthy,

Thanks for your feedback. With that noted, I would suggest my first recommended device LMR33630.

LMR33630ADDAR is perfectly suited for our application for 5V 3A.

Please provide an application schematic with Inductor and Capacitor values for 12V 3A Using LMR33630ADDAR 400kHz.

Please Suggest one more IC 5V,5A in this package.

Regards
Murthy

Murthy,

Please take a look at the Typical Application Section in the datasheet which provides the typical components for your specific conditions in which you are requesting.

For the 5-A application, is the VIN range still the same of 6V to 28V?

Alejandro

Yes 5V I know, I asked for 12 V DC output.

Please provide an application schematic with Inductor and Capacitor values for 12V 3A Using LMR33630ADDAR 400kHz.

Input Voltage : 16 to 26 V

Murthy,

The typical application section provides the following info:

Also, I recommend using our WEBENCH tool which creates customized power supply circuits based on your requirements. The WEBENCH tool for this device can be found at the bottom of the product folder under Design & Development.

For the 5VOUT 5A application see: TPS5450.

Alejandro

Murthy,

As recommend previously, using our WEBENCH tool will help create/customize power supply circuits based on your requirements. The WEBENCH tool for this device can be found at the bottom of the product folder under Design & Development. Also, the datasheet provides a detailed procedure section to select the appropriate components.

You will need a buck-boost product for the following application below. Unfortunately, that is outside of my department. Therefore, I recommend to post another thread in the forum and the correct department will be able to help.

Input Voltage: 16 V DC to 26 V DC
Output voltage: 24 V DC
Output Current: 5A.

Thanks,
Alejandro

Murthy,

I would also like to add that for your 5VOUT 5A application, LMR14050 would be a great fit. It has a slight higher efficiency of around +4%.

Alejandro
