Product Specifications: Input: 12.5-75V Output: 43V 7A
LT8708 step-down mode, input 48V output 43V, load > 0.3A burning MOSFET
With load M1 M2 MOSFET damage, short circuit
No-load output voltage is normal, input 12V boost output 43V is normal
However, at 48V input and 43V output, the MOSFET with the load of M1 M2 is damaged and transmitted, short circuit
What is the cause of this problem?
