EV1412-0600-A
Introduction
This user guide describes the evaluation board provided for the FS1412 µPOL™ product.
The board generates an output voltage (VOUT) of 1V for loads of 0–12A from an input voltage (PVIN) of 12V.
Specifications
Input voltage (PVIN) = +12V
Output voltage (VOUT) = +1V
Output load (IO) = 0–12A
Switching frequency (FSW) = 1.0MHz
Output capacitance (CO) = 4x47µF (MLCC)
Input capacitance (CIN) = 3x22µF (MLCC)
Dimensions (width x length x thickness) = 61mm x 89mm x 1.6mm

The board is configured for a single input supply. An internal low drop-out regulator generates the internal
supply (VCC) from VIN. The Enable (En) input is connected to PVIN through a resistor divider, so that no external
Enable signal is needed.
Operation
To use the evaluation board:
1. Connect a well-regulated +12V input supply to PVIN (J1) and Gnd (J4).
2. Connect a load of 0–12A to VOUT (J3) and Gnd (J2).

Description
The evaluation board consists of a 4-layer PCB made from FR4 glass-reinforced epoxy laminate material. All
layers use 2oz copper (equating to a thickness of 0.0694mm). The major power components, including the
FS1412, are mounted on the top side of the board.
