HIP1012A
Exploring and Using the HIP1012EVAL1
Board (Figures 13 and 14)
The HIP1012EVAL1 is a flexible platform for a thorough
evaluation of the HIP1012A dual power supply controller.
This eval board comes in three separate parts allowing the
evaluation of two principal configurations. To simulate a
passive back plane implementation both the GENERIC and
LOAD sections are first connected together and then the
GENERIC board is connected onto the BUS board. For an
active backplane or for the HIP1012A on an interposer board
LED’s. The resistive loads are configured so that either no
current, a low or high current load relative to the OC trip
point can be invoked for both supplies. An OC event can be
emulated by switching both switches of any one output to the
on position (see Table 4, OC conditions highlighted). Load
connection sequencing can be done by shorting the desired
finger lengths. As noted, the GENERIC board is default
configured for 3V and 5V operation. For 12V evaluation
replace RL3 and RL4 with a suitable load.

SWAP mode. PWRON1 only controls reset

The BUS board is designed so that adding suitable
connectors and/or power supply capacitive filtering is very
easy to do through the numerous through holes for each rail
voltage and ground. Passive backplane power sequencing
can be simulated by simply shortening the finger lengths for
the rail(s) that need to come up after initial ground
connection is made.
The GENERIC board, is a flexible evaluation platform with
many designed in features for user customizing and
evaluation. The circuit is shipped default configured in the
3.3V and 5V controller mode by jumpers for easy
reconfiguration (see Table 3 for jumper settings). The default
configuration is highlighted in Table 3. The default OC levels
are 5A on the 3.3V and 1A on the 5V supplies. To operate
the HIP1012 GENERIC board in its default configuration (3V
and 5V) a dedicated +12V power supply must be provided

current load needs to be provided. A programmable
electronic current load is an excellent evaluation tool for this
device. The load board is configured to sink about 3A ± 1A at
3.3V. For 12V operation, the load must be modified to sink
less than 5A, otherwise, an OC failure upon power will occur.
