... Connect the PHASE pin to the PWM converter’s upper MOSFET source. This pin is used to monitor the voltage drop across the upper MOSFET for over-current protection. 6 HIP6018B UGATE1 (Pin 24) Connect UGATE pin to the PWM converter’s upper MOSFET gate. This pin provides the gate drive for the upper MOSFET ...

... Description Operation The HIP6018B monitors and precisely controls 4 output voltage levels (Refer to Figures 1, 2, and 3 designed for microprocessor computer applications with 3.3V and 5V power, and 12V bias input from an ATX power supply. The IC has one PWM controller, a linear controller, and a linear regulator ...

... With OUT1 still overloaded, the inductor current increases to trip the over- current comparator. Again, this inhibits all outputs, but the 8 HIP6018B soft-start voltage continues increasing to 4V before discharging. The counter increments to 2. The soft-start cycle repeats at T3 and trips the over-current comparator. The SS ...

... Contact Intersil for evaluation board drawings of the component placement and printed circuit board. There are two sets of critical components in a DC-DC converter using a HIP6018B controller. The power components are the most critical because they switch large amounts of energy. The critical small signal components connect to sensitive nodes or supply critical by-passing current ...
