7) Use heavy copper traces: this will reduce their resistance, increasing overall efficiency and will improve
their heat-sinking ability.
L5994 Evaluation Kit
The L5994 Evaluation kit is a fully assembled and tested demonstration board that implements a standard ap-
plication circuit, configured according to the following specifications:
Input Voltage Range: 5V to 25V;
3.3V Output: Iout3 = 3A;
5.1V Output: Iout5 = 3A;
12V Output: Iout12 = 50mA;
Switching frequency: fSW = 300kHz.
