Description:
The NCP1606B is an active power factor controller specifically designed for use as a pre−converter in electronic ballasts, ac−dc adapters and other medium power off line converters (typically up to 300 W). It embeds a Critical Conduction Mode (CRM) scheme that substantially exhibits unity power factor across a wide range of input voltages and power levels. Housed in a DIP8 or SOIC−8 package, the NCP1606 minimizes the number of external components. Its integration of comprehensive safety protection features makes it an excellent driver for rugged PFC stages.
General Features:
1. “Unity” Power Factor
2. No Need for Input Voltage Sensing
3. Latching PWM for Cycle by Cycle On Time Control (Voltage Mode)
4. High Precision Voltage Reference (±1.6% over temperature ranges)
5. Very Low Startup Current Consumption (≤40 A)
6. Low Typical Operating Current (2.1 mA)
7. -500 mA / +800 mA Totem Pole Gate Driver
8. Undervoltage Lockout with Hysteresis
9. Pin to Pin Compatible with Industry Standards
Typical Application Circuits :
Applications:
1. Electronic Light Ballast
2. AC Adapters, TVs, Monitors
3. All Off Line Appliances Requiring Power Factor Correction
