APW1175

APW1175 Dual Synchronous DC/DC Controllers with Current Sharing Control Features General Description Two Operation Modes - Independent Operation - Two-Phase Operation with Current Sharing Driving N-Channel MOSFETs 300kHz Constant Frequency Operation Built-in Feedback Compensation - Voltage-Mode PWM Control - Fast Transient Response ±1% VREF Accuracy Over Temperature Adjustable Output Voltage by an External Resistor  Divider Phase-Shifted Switchers to Minimize Ripple Current Limit with 50% Fold-Back The APW1175 is a two-phase, synchronous, and voltage mode PWM controller to provide dual channel or single outputs in two distinct operation modes. In independent mode, the two PWM converters supply two independently regulated voltages by converting a common or two different power inputs. In two-phase mode, the two PWM converters supply one regulated voltage with programmable current sharing control by converting a common or two different power inp...
