■

The SSC2000 series products are power factor correction (PFC) controller ICs of

Continuous Conduction Mode (CCM). The product achieves high power CCM systems,

with few external components and no multiplier by the average current control method.

General Descriptions

Features

Applications

Product Lineup

Continuous Conduction Mode (CCM)

The mode enables the low peak current recommended for high power supplies.

Average Current Control Method

The method requires no input line voltage sensing and no multiplier,

and achieves simple systems with few external components.

Pulse Width Modulation (PWM) + Frequency Modulation Function

The function superposes the modulated frequency according to Duty value, on the internally fixed PWM

frequency of 65 kHz(TYP).

Maximum Duty Cycle : 94% (TYP)

Built-in High Speed Response for Dynamic Load Changes

Error Amplifier Reference Voltage : 3.5V (TYP)

Brown-In / Brown-Out Function

The function enables the oscillation start/stop by externally rated input voltage

and makes protections at low input voltage.
