Overview: NCP1600 High Voltage PFC Controller with Standby Power Saving
The NCP1600 is an active power factor correction controller that 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.
The NCP1600 can achieve deliver follow−boost operation that is 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.
