Cool-Power^TMSeries



36-75V Input, 3.3V / 18A / 60W Output

Very High Density Isolated DC-DC Converter (400W/in³)

Description

The Cool-Power^TMPI3101 is a very high density

Features

isolated DC-DC converter implementing a high

efficiency soft-switching power architecture. The

PI3101 operates over a wide range input of 36V to

75Vdc, delivering ~60W of output power (3.3Vout @

18A), yielding an unprecedented power density of

400W/in³. The PI3101 is available in a space saving

surface mountable 0.87” x 0.65” x 0.265” package,



Efficiency up to 87%

High switching frequency minimizes input filter

requirements and reduces output capacitance

Proprietary “Double-Clamped” ZVS Buck-Boost

Topology

Proprietary isolated magnetic feedback

Small footprint (0.57 in²) enables PCB area

savings

Very low profile (0.265 in)

Wide input voltage range operation (36-75Vdc)

On/Off Control, positive logic

+10/-10% Trim

Temperature Monitor (TM) & Over-Temperature

Protection (OTP)

Input UVLO & OVLO and output OVP

Over current protection with auto restart

Adjustable soft-start



achieving

~50%

space

reduction

versus

conventional solutions.



The switching frequency of 900kHz allows for small

input and output filter components which further

reduces the total size and cost of the overall system

solution. The output voltage is sensed and fed back

to the internal controller using a proprietary isolated

magnetic feedback scheme which allows for high

bandwidth and good common mode noise immunity.

The PI3101 requires no external feedback

compensation and offers a total solution with a

minimum number of external components. A rich

feature set is offered, including output voltage trim

capability, output over-voltage protection, adjustable

soft-start, over-current protection with auto-restart,

over and under input voltage lockout and a

temperature monitoring and protection function that

provides an analog voltage proportional to the die

temperature as shut down and alarm capabilities.
