AW7016

The APW7016 provides a complete control and protection for a DC-DC converter optimized for high performance microprocessor applications. It is designed to drive two N-Channel MOSFETs in a synchronousrectified buck topology. The APW7016 integrates output voltage control , monitoring and protection functions into a single Package.

The APW7016 includes a 3-bit digital-to-analog converter (DAC) that provides a easily adjustable and precisely output voltage from 1.3V_DC to 1.65V_DC in 0.05V steps. Any selected output voltage can be maintained within ±1% accuracy over temperature and line voltage variations.

With a 200kHz free-running triangle-wave oscillator and a error amplifier featuring a 15MHz unity-gain bandwidth and 6V/us slew rate inside the chip ,APW7016 can implement a simple , single feedback loop , voltage-mode control topology with high transient performance.

The APW7016 also features with multiple protections against over-current and over-voltage conditions by inhibiting PWM operation. The APW7016 uses the R_DS(ON) of the upper MOSFET as the current sensing element which eliminates the demend for an extra component. The APW7016 also monitors the output voltage using a comparator with hysteresis that tracks the DAC output.
