Application Note AN9888
After the initial over-current trip, the HIP6302 waits for a
Summary
period of time equal to 2048/f SW (f SW is the switching
frequency) before initiating a soft-start cycle. If the over-load
condition remains, another over-current trip will occur before
the end of the soft-start sequence. This repetitive over-
current cycling is illustrated in Figure 8, and will continue
inde?nitely unless the fault is cleared or power to the
converter is removed. Because of the wait period, the worst
case power delivered during overcurrent cycling is equal to
45% of the power delivered during normal operation at full
load. Therefore, inde?nite over-current cycling does not
create a thermal problem for the circuit.
The HIP6302EVAL1 is intended to provide a convenient
platform to evaluate the performance of the HIP6302 -
HIP6601A chip set in the speci?c implementation indicated
in Table 1. The design demonstrates a favorable trade off
between low cost, high ef?ciency, and small footprint. The
following pages include schematic, bill of materials, and
layout drawings to facilitate implementation of this solution.
The evaluation board is simple and convenient to operate,
and test points are available to evaluate the most commonly
tested parameters. Example waveforms are given for
reference.
The HIP6302 and HIP6601A provide a versatile 2-phase
OUTPUT CURRENT, 20A/DIV
power solution for low-voltage applications from 25A to
approximately 40A, and together they result in the most
effective solution available.
