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 :
