Hi
We are planning to use LT8471 chip for providing VCC to opamp i.e. operating at 12V and -12V
Is this IC is able to provide 12V,2A and -12V ,250mA or 500mA.
We are going to use this 12V,2A into designing 5V/1A 3.3 V/2A and 1.8V/1A using LT3514 chip.
We are using 24V/2A adaptor to provide input to LT8471 chip.
Can you please help in this.
If any application note is available please provide.
Hi
Yes it is possible, Please refer to the design example on page 30 of LT8471 as starting reference for your design.
note: it is recommended to optimize the operating frequency and inductor to give headroom for the current limit of the positive rail
