Description
The uP6111A/B is a high performance synchronous-rectified buck controller specifically designed for POL voltage regulation in notebook PC application.
Features
- easy-to-use, low external component count, fast transient response and quasi constant frequency operation over the operation range. Selectable Forced Continuous Conduction Mode (FCCM) or Power Saving Mode (PSM) enables the flexibility for low noise operation or high efficiency conversion over wide output current range. Lossless current sensing by RDS(ON) of lower switch achieves programmable over current protection. Other features include internal soft start, integrated bootstrap diode and therm.
