NEED design steps for LT3479

Hi Amol,

Please review the datasheet especially the Operation and Applications Information to know more how to design your circuit. However, based on the typical applications, 3A might be too high for this chip and it might affect efficiency.

I would suggest to try another boost controller such as LTC7804: LTC7804 Datasheet and Product Info | Analog Devices. There is an available LTpowerCAD model to help you in the design process.

Hi Ron,

thanks for reply,

my application uses standby current of 150uA, hardly get activated for 25 seconds that to with average current of 1A, peak current of 3A only for 50ms & peak current instances no more than 10 times with gap of 1.5 second

let me know, if you still have any better option with internal FET & (currently available on online portal)
