... Functional Description Initialization The HIP6007 automatically initializes upon receipt of power. Special sequencing of the input supplies is not necessary. The Power-On Reset (POR) function continually monitors the input supply voltages and the enable (EN) pin. The POR monitors the bias voltage at the VCC pin and the input voltage ( the OCSET pin ...

... Please note that the capacitors C and C Locate the HIP6007 within 3 inches of the MOSFETs, Q1. The circuit traces for the MOSFETs’ gate and source connections from the HIP6007 must be sized to handle peak current. Figure 6 shows the circuit traces that require additional OCSET layout consideration ...

... Given a sufficiently fast control loop design, the HIP6007 will provide either 0% or 100% duty cycle in response to a load transient. The response time is the time required to slew the inductor current from an initial current value to the transient current level ...

... MOSFET power loss (see the equations below). These equations assume linear voltage- current transitions and are approximations. The gate- charge losses are dissipated by the HIP6007 and don't heat the MOSFET. However, large gate-charge increases the switching interval which increases the upper SW MOSFET switching losses ...
