EC3228 Overview
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
