SSC1S312A - Quasi-Resonant Off-Line Switching Controller

Download the SSC1S312A datasheet PDF. This datasheet also covers the SSC1S310A variant, as both devices belong to the same quasi-resonant off-line switching controller family and are provided as variant models within a single manufacturer datasheet.

General Description

SSC1S310A series is the controller ICs of a quasiresonant mode for a switching power supplies.

The IC incorporates a startup circuit and a standby function to reduce a power consumption and standby power.

In normal operation, the quasi-resonant mode operation achieves high efficiency and low noise.

Key Features

  • Features.
  • Multi-Mode Control (High efficiency operation in all range of loads).
  • Automatic Standby Function (Standby power is inproved by burst oscillation mode).
  • Input Power at No Load:.

Quasi-Resonant Off-Line Switching Control ICs SSC1S310A Series Data Sheet Description SSC1S310A series is the controller ICs of a quasiresonant mode for a switching power supplies. The IC incorporates a startup circuit and a standby function to reduce a power consumption and standby power. In normal operation, the quasi-resonant mode operation achieves high efficiency and low noise. In addition, in medium to low load conditions, the operation mode is automatically changes the quasi-resonant mode to the bottom-skip mode to improve efficiency. The IC is provided in the SOIC8 package. The power supply that is a low component counts and a high performance-tocost can be achieved by the rich set of protection features.
