SSC2101S

Power Factor Correction

Discontinuous Conduction Mode Controller

Features and Benefits

Description

▪ Interleaved Discontinuous Conduction Mode (DCM)

operation: low peak current, low ripple current, and low

noise; for medium- to high-power applications

▪ Constant Voltage Mode control: no auxiliary windings

required on inductors because of the built-in arithmetic

circuit; achieves a simple PFC system

• Maximum on-time: 15 μs (typ)

▪ Built-in Soft Start function: reduces stress on power

devices at startup

The SSC2101S is a controller IC intended to implement

a Discontinuous Conduction Mode (DCM) interleaved

Power Factor Correction (PFC) circuit. Using the two-phase

interleaved control incorporated in this IC, it is possible to

achieve a low cost, high performance PFC system with low

input/output ripple currents, low noise, and few external

components.

▪ Built-in High Speed Response (HSR): suppression of

output voltage changes during dynamic load transients

▪ Error Amplifier reference voltage: 3.5 V (typ)
