... Functional Description Initialization The HIP6013 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 ...

... Locate the HIP6013 within 3 inches of the MOSFETs, Q1. resistor OCSET The circuit traces for the MOSFETs’ gate and source connections from the HIP6013 must be sized to handle peak current. Figure 6 shows the circuit traces that require additional , layout consideration. Use single point and ground plane ...

... 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 HIP6013 and don't heat the MOSFET. However, large gate-charge increases the switching interval which increases the upper SW MOSFET switching losses ...

... The figure below shows a DC-DC converter circuit for a microprocessor application, originally designed to employ the HIP6007 controller. Given the similarities between the HIP6007 and HIP6013 controllers, the circuit can be implemented using the HIP6013 controller without any modifications. However, given the expanded reference voltage ...
