I am evaluating buck converters between TI parts. As I reviewed the specs between 82085 and 82671,
they are compatible in terms of input voltages, operating frequency (2.4 vs. 5.5Mhz) and etc. However,
the operating quiescent current is totally different between them. On the condition, devices are NOT
switching, they are identical, but 82671 jumps to 5.8mA as Iout = 0 in PWM mode (show below). The 82085 device
is also the similar scheme for power conversion, but it does not show any data in supply current category.
I would like to know the value of 5.8mA (shown above) as typo or real data during PWM operation. If it is in
PWM, why 82085 does not have any similar current consumption during this operation.
I am looking forward to hearing from you.
Warm Regards.
