Product Description
The Cool-PowerTM PI3101 is a very high density isolated DC-DC
converter built on a proprietary ZVS topology using advanced control
silicon integration, state of the art planar magnetics and high
performance power semiconductor technology enabling high
switching frequencies.
The PI3101 operates over a wide range input of 36 V to 75 Vdc,
delivering 60 W of output power (3.3V @ 18 A), yielding an
unprecedented power density of 400 W/in3. The PI3101 is available in
a thermally enhanced, surface-mount Power-System-in-Package (PSiP)
that is just 0.57in2 and very low profile (0.265”), enabling space
savings of over 50% versus conventional solutions.
The high switching frequency of the PI3101 allows for small input and
output filtering components, further reducing size and cost of the
overall system solution.
The PI3101 is fully equipped with a variety of programmable features
including: +/-10% output voltage trimming, programmable soft-start
capability, remote on / off ENABLE and an accurate temperature
monitor function that provides an analog output voltage proportional
to the internal temperature of the product, serving also as a fault
alarm. The PI3101 is self-protected against various fault conditions
including: input over-voltage and under-voltage lockout with autorestart capability, over-temperature and output over-voltage protection
with auto-restart capability and a dual current limit threshold to
protect against short circuits and overload conditions.
