Dear all,
Could you teach me how to improve stability at cold condition (-40C)?
*We tested with EVM. Please see attached file.circuit diagram.pdf
**At room / hot temperature, this worked well. But this did not output at cold temperature and 8A load.
***I wonder if the slope setting is not good.
Could you teach me recommendation of the value of passive devices?
■CONDITION
・Vin = 6V~12V
・Vout = 12.5V
・Fsw = 350kHz (FPWM)
・Iout = 8A(max)
・designated Inductor = 1.5uH (panasonic: ETQP6M1R5YLC)
Best regards,
