Y-PWR
Hot Swap, Load Sharing Controller
Quick Installation Guide
Version 1.0a
P/N Y-PWR
Introduction
The Y-PWR is a 20A, 30V ideal diode OR controller. Two power sources such as AC/DC
adapters of equal voltage can be used to sum (load sharing) the output power into a single,
high power channel. This versatile device can be used as a Hot Swap, Load Sharing / High
Availability or Power Path Controller resulting in a low loss, high efficiency solution for
AC/DC and/or battery solution.

Quick installation Instructions
1. Connect the 1st power source to Input_1
2. Connect the 2nd power source to Input_2
3. Connect the output of Y-PWR to input of your device.
Typical configurations
The Y-PWR is a versatile power path controller. Here are several configuration scenarios:
1. Summing two power sources: If input_1 and input_2 have the same output
voltage, the Y-PWR board can integrate the current from both inputs, up to 10A
per channel. Small differences in output voltage are OK as the internal resistance
of the wires will tend to equalize the load. As the two supplies differ by more than
100mV, 100% of the load will come from the higher of input_1 and input_2.
2. HOT SWAP: Two input power source can be hot-swapped without any power
loss at the output.
3. AC/DC adapter + battery scenario: the higher voltage will always get routed at
the output. For example, if the AC/DC adapter is set for 16V and the SLA battery
is at 13.5V, the 16V input will always get routed to the output. Once the AC/DC
source drops below 13.5V, the battery will automatically get routed to the output.
When the AC/DC voltage reaches a voltage above battery voltage the power
path will be automatically switched to the highest voltage.
4. For more sophisticated operation, each channel can be fully blocked via control
pins such as control from a microprocessor. Please consult the schematic
(see Vprim and Vsec control) for more information regarding control of the
device.
