Description: Dual-Phase / Quick-PWM Controller

Features

* o Dual-Phase, Quick-PWM Controller o ±0.75% VOUT Accuracy Over Line, Load, and Temperature (1.3V) o Active Voltage Positioning with Adjustable Gain and Offset o 5-Bit On-Board DAC: 0.675V to 1.55V Output Adjust Range o Selectable 100kHz/200kHz/300kHz/550kHz Switching Frequency o 4V to 28V Battery In

Applications

* stepping down the battery directly or stepping down the 5V system supply to create the core voltage. The single-stage conversion method allows this device to directly step down high-voltage batteries for the highest possible efficiency. Alternatively, two-stage conversion (stepping down the 5V syst
