... Efficiency Figure 2 displays the HIP6004EVAL3 efficiency versus load current for both 5V and 12V inputs and a 2.8V output with 100 linear feet per minute (LFM) of airflow. The converter efficiency is equal to the output power divided by the input power, which consists of the output power plus losses ...

... MOSFET switching losses and is displayed in Figure 2. Transient Response Figures 3 and 4 show laboratory oscillograms of the HIP6004EVAL3 in response to a load transient application. The load transient applied is from 0A to 14A for both figures. In Figure 3, the transient is applied using an Intel test tool which emulates the actual dynamic performance of the Pentium II and other future processors ...

... Transient Response Figures 6 and 7 show laboratory oscillograms of the HIP6005EVAL3 which are similar to those shown in Figures 3 and 4 for the HIP6004EVAL3. There are small differences in the transient responses of the two different evaluation boards. Since the HIP6005EVAL3 uses a larger output inductor and identical control loop compensation (R5, R8, C8, and C9), the closed-loop gain crossover frequency is lower than for the HIP6004EVAL3 ...

... See the Over-Current Protection section of either the HIP6004 and HIP6005 data sheet for details on the design procedure for the OCSET resistor. Enable Function The HIP6004EVAL3 and HIP6005EVAL3 can be disabled by pulling the SS pin below 1.2V. A simple way to incorporate an open collector ENABLE function is shown in Figure 9. HIP6004 ...
