见下面一段话,红字指的就是你说的放大器
Current Mode
The current mode scheme is a sequence of feedback control described as follows. The output voltage is
monitored at the middle point of voltage divider resistors and fed back to a transconductance amplifier. The
amplifier outputs target current level proportional to error amount between the feedback voltage and the internal
1 V reference voltage. The inductor current level is monitored during the off-cycle, when rectifying MOSFET is
turned on. |
