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

Overview

uP6111A/B Single Phase PWM Controller for Mobile Applications General.

Key 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.
