uP6111A/B
Single Phase PWM Controller for Mobile Applications
General Description
The uP6111A/B is a high performance synchronous-rectified buck controller specifically designed for POL
voltage regulation in notebook PC application.
The controller operates with 5V bias
voltage and converts 2V~26V input
voltage to 0.
75V~5.
5V output
voltage.
The uP6111A/B adopts constant-on-time PWM scheme that 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 w...
