EC3228 Description

Features The EC3228 is a single-phase, constant-on-time, synchronous PWM controller, which drives N-channel MOSFETs. The EC3228 steps down high voltage to generate low-voltage chipset or RAM supplies in notebook puters. The EC3228 provides excellent transient response and accurate DC voltage output in either PFM or PWM Mode.

EC3228 Key Features

  • synchronous PWM controller, which drives N-channel
  • generate low-voltage chipset or RAM supplies in notebook
  • puters
  • Pulse Frequency Mode (PFM), the EC3228 provides very
  • high efficiency over light to heavy loads with loading
  • modulated switching frequencies. In PWM Mode, the
  • converter works nearly at constant frequency for low-noise
  • requirements
  • The EC3228 is equipped with accurate positive current
  • limit, output under-voltage, and output over-voltage

EC3228 Applications

  • Reset function monitors the voltage on VCC to prevent
