SC416
Overview
The SC416 is a versatile, constant on-time, pseudofixed-frequency, dual synchronous buck PWM controller intended for notebook computers and other battery operated portable devices. The SC416 contains all the features needed to provide cost-effective control of two independent switchmode power supplies.
- Preset Output Voltages: VOUT1 = 1.8 or 1.5V VOUT2 = 1.25 or 1.05V
- Proportional or Coincident Tracked Start-up and Shutdown of Both Outputs
- Adjustable Soft-start Rates for Each Output
- Regulated Shutdown for Each Output
- Low Shutdown Power
- Constant On-Time for Fast Dynamic Response
- Adjustable Switching Frequency
- Separated Frequencies for Minimal Switching Interaction: VOUT1 = up to 600kHz VOUT2 = up to 720kHz
- Power Save or Continuous Operation at Light Load
- Over-Voltage and Under-Voltage Fault Protection
