Application Example
SENZero in PFC Bus Voltage Feedback Network
Commercial PFC IC’s typically has a pin dedicated for sensing
the output voltage of the PFC Stage. The information on this
pin is typically used by the PFC IC for various major functions.
1. Output regulation – input to the non-inverting input of the
error amplifier
2. OVP detection - input to the OVP comparator
3. Open loop protection – used to detect open loop conditions
The last 2 functions were used for protecting the bus from
overvoltage condition.
Figure 10. PFC Bus Voltage Sense Network.
The SENZero objective is to eliminate the losses associated
with the sense resistors without affecting the functionality of the
circuit. To keep the operation of the PFC IC unaffected,
SENZero and PFC on and off event must follow the required
timing sequence during power-up, power-down, remote-on,
and remote-off event.

Figure 11. Timing between PFC IC and SENZzero during Power-up and
Power-Down.
In case of shared VCC Connection, it must be ensure that
SENZero have a lower turn-on and turn-off threshold voltage
compared to the PFC IC.
Figure 12. Timing between PFC IC and SENZero with PS
(ON) Signal.
From off-state to on-state, SENZero must turn-on ahead of the
PFC. From on-state to off-state, PFC must shutdown ahead of
the SENZero. This is to ensure that whenever PFC is operating
(switching), SENZero is invincible to the PFC. SENZero only
disconnects the sense resistors when PFC is in off-condition
and thus eliminates its associated losses during standby
condition.
