The HIP6013 provides complete control and protection for a DC-DC converter optimized for high-performance microprocessor applications. It is designed to drive an N-Channel MOSFET in a standard buck topology. The HIP6013 integrates all of the control, output adjustment, monitoring and protection functions into a single package.

The output voltage of the converter can be precisely regulated to as low as 1.27V, with a maximum tolerance of ±1.5% over temperature and line voltage variations.

The HIP6013 provides simple, single feedback loop, voltagemode control with fast transient response. It includes a 200kHz free-running triangle-wave oscillator that is adjustable from below 50kHz to over 1MHz. The error amplifier features a 15MHz gain-bandwidth product and 6V/µs slew rate which enables high converter bandwidth for fast transient performance. The resulting PWM duty ratio ranges from 0% to 100%.

The HIP6013 protects against over-current conditions by inhibiting PWM operation. The HIP6013 monitors the current by using the r_DS(ON) of the upper MOSFET which eliminates the need for a current sensing resistor.
