... The HIP6014 monitors the output voltage with a window comparator that tracks the DAC output and issues a Power Good signal when the output is within 10%. The HIP6014 protects against over-current and over-voltage conditions by inhibiting PWM operation. Additional built-in over-voltage protection triggers an external SCR to crowbar the input supply ...

... Functional Description Initialization The HIP6014 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. The POR monitors the bias voltage at the V pin and the input voltage (V CC OCSET pin ...

... A small ceramic capacitor should be placed in parallel with R to smooth the voltage across R OCSET presence of switching noise on the input voltage. Output Voltage Program The output voltage of a HIP6014 converter is programmed to discrete levels between 1.8V and 3. HIP6014 little power with this method. The measured input power for the conditions of Figure ...

... Figure 5 should be located as close together as possible. Please note that the capacitors C and C each represent numerous physical capacitors. O Locate the HIP6014 within 3 inches of the MOSFETs, Q and Q . The circuit traces for the MOSFETs’ gate and 2 source connections from the HIP6014 must be sized to handle peak current ...

... Standard-gate MOSFETs are normally recommended for use with the HIP6014. However, logic-level gate MOSFETs can be used under special circumstances. The input voltage, upper gate drive level, and the MOSFET’s absolute gate-to- source voltage rating determine whether logic-level MOSFETs are appropriate. ...
