Datasheet
NCP1600
High Voltage PFC Controller
with Standby Power Saving
operates as a boost pre−converter in off−line power supply
applications. NCP1600 is optimized for low to medium power,
high−density power supplies requiring a minimum board area,
reduced component count and low power dissipation. Two
comparators are built into this device to improve standby (power)
efficiency. With these two comparators, the PFC controller
automatically switches itself in between normal mode and standby
mode (skip or off mode) to save power consumption during light load
conditions.
an innovative mode allowing a drastic size reduction of both the
inductor and the power switch. Ultimately, the solution system cost is
significantly lowered. NCP1600 can also work in a traditional
constant output voltage mode and intermediate solutions can be
easily implemented. This flexibility makes it ideal to optimally cope
with a wide range of applications.
