Definitions
- the present invention relates to active diodes, and more particularly, to a technique for turning off a transistor switch of an active diode.
- the off controller may further include a delay unit configured to delay the inversion signal of the gate driving signal and output the delay signal to the D flip-flop.
- the comparator 100 senses the VKA voltage and determines whether it is positive or negative.
- VKA is negative
- VKA_NEG becomes high
- VKA_NEG becomes the S (set) input of the SR latch 320
- the output of the SR latch 320 also becomes high. Therefore, the input signal IN of the gate driver 200 becomes high and M1 is turned on.
- the off controller 310 is an off-control circuit and generates a TOFF signal using a signal obtained by inverting the gate driving signals VG and VKA_NEG.
- FIG. 5 illustrates an operation timing diagram of an off-control circuit according to an embodiment of the present invention.
