SDC2921 - Voltage Mode PWM Controller

Download the SDC2921 datasheet PDF. This datasheet also covers the SDC2921-en variant, as both devices belong to the same voltage mode pwm controller family and are provided as variant models within a single manufacturer datasheet.

Features

  • The SDC2921 is a Pulse.
  • Width Modulation (PWM) control circuit with complete protection circuits for the SMPS T(Switching Mode Power Supply). It contains various Nfunctions, can minimize external components of switching OCUMEpower supply systems in personal computer.
  • Complete PWM control and protection circuits.
  • Over voltage protection for 3.3V/ 5V/ 12V/ PT.
  • Under voltage protection for 3.3V/ 5V/ 12V.
  • 280ms PG time delay.
  • Open drain power good output.
  • 280m.
