Product Number: LT1171
Hi,
I have the following requirements
Input operating voltage = 30V to 100V
Output voltage = 28V
Load Current = 1A
Operating frequency 500KHz.
As I have the PCB space constraints I have used minimal essential components required.
When I operate the device below 25V, the ouput is same as input, but when I increase the voltage the device is getting damaged.
As I see in the datasheet, 100 duty cycle should be avoided when output voltage is above 16V, So I tried by applying 40V directly. Then also remains same issue.
Please suggest solution for this issue.
I am attaching the schematic for your reference
Thanks in advance
