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.
Features
• Lose Less High−Voltage Startup Source
• Standard Constant Output Voltage or “Follow−Boost” Mode
• PFC Skip Mode and Off Mode under Light Load Conditions
• Selectable Switching Frequency Clamp
• Disable Pin to Stop PFC Operation
• Restart Delay Timer
• Brown−out Protection for Startup
• Feedback Loop Open Detection
• Output Overvoltage Comparator
• Switch Mode Operation: Voltage Mode
• Constant On−Time Operation That Saves the Use of an Extra
Multiplier
• Improved Regulation Block Dynamic Behavior
• Internally Trimmed Reference Current Source
• Internal Leading Edge Blanking (LEB) for Noise Immunity
Typical Applications
• Monitor/TV Power Supplies
• PC Power Supplies
• Notebook PC Adapters
• Medium Power Adapters
