NCP1606 Datasheet (ON Semiconductor) - Cost Effective Power Factor Controller

NCP1606, Cost Effective Power Factor Controller

Pin Number Name Function 1 Feedback (FB) The FB pin makes available the inverting input of the internal error amplifier.

A simple resistor divider scales and delivers the output voltage to the FB pin to maintain regulation.

The feedback information is also used for the programmable overvoltag

DATA SHEET www.onsemi.com Cost Effective Power Factor Controller NCP1606 The NCP1606 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 SOIC 8 package, the NCP1606 mini
