ADP5052 Simulation Individual channels

Pratik Shirore on Dec 3, 2020

Dear Team,

I am trying to simulate the device ADP5052 based on the reference schematic provided in datasheet. But the simulation module in LT Spice software has only one channel in the output. as shown below. How to simulate 2 different channels (Channel 1 & Channel 2 at same time.) & how to achieve the soft start delay between CH1(2ms) & CH2(8ms). Same is the case with CH3 & CH4 module of ADP5052.

LT Spice Model Sample Circuit Soft Start

Kindly help me with same.

Thanks & Regards

Hi

The model is currently optimized in simulating the operation of either CH1 or CH2 at steady state.

Please perform bench verification for the different timings for start up

Hi Pratik,

I will request to improve the LTspice model to have 2 channels in one box but this will take time. Mikee's recommendation is best for now. If you can share to me project details and estimate annual usage, I can send you demo board to test.

Hi,

Thank you for reply.

It means I have to Configure Rtop & Rbot resistor separately for individual timing sequence of 2ms & 8ms.
