EV1703-3300-A  
Introduction  
This user guide describes the evaluation board provided for the FS1703 µPOL™ product.  
The board generates an output voltage (VOUT) of 3.3V for loads of 0–3A from an input voltage (PVIN) of 5V.  
Specifications  
Input voltage (PVIN) = +5V  
Output voltage (VOUT) = +3.3V  
Output load (IO) = 0–3A  
Switching frequency (FSW) = 580 kHz  
Output capacitance (CO) = 3x22µF (MLCC)  
In put capacitance (CIN) = 2x22µF (MLCC)  
Dimensions (width x length x thickness) = 63 x 84 x 1.5mm

The board is configured for a single input supply. An internal low drop-out regulator generates the internal supply (VCC)  
from PVIN. The Enable (En) input is connected to PV through a resistor divider, so that no Enable signal is needed.

Operation  
To use the evaluation board:  
1. Connect a well-regulated +5V input supply to PVIN (J1) and GND (J2).  
2. Connect a load of 0–3A to VOUT (J8) and GND (J7).

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 FS1703, are mounted  
on the top side of the board.
