Thanks for the reply. I found that some of the pins which were not supposed to be connected to the ground, were falsely connected to the ground. With the previous experience, I have found that the chip works fine when not soldered on the board, that is, the chip generates some voltages at the...
Hi,
Please check the schematic with the component values.

Hi,
I have replaced the old IC LTC4020 chip with a new one. Again, it is not working. Also, when the new chip was tested separately, it worked fine and generated four PWM signals at four pins TG1, BG1, TG2, and...
Hi,
Please check the attachments for my 4-layer design. Note that there is a rectifier circuit before the converter and the rectifier works fine producing DC voltage above 4.5 V. And now I am trying to test the converter individually by isolating it from the rectifier.
I will try to measue...
Hi,
I have designed and implemented the hardware of a DC/DC buck boost converter and charger with the IC LTC4020. However, I am not getting the output as desired 12 V DC, instead getting the output as 0 V. Apparently, the system does not work.
On checking the PWM signals from the pins of the...
