Component recommendation and PCB layout
In order to largely avoid electromagnetic interference pin 2 (V
S), VIN and the drain of the
driven MOSFet should be directly connected to C
IN1. In a similar manner pin 14 (SRC),
the source of the transistor, the bootstrap capacitor C
BT and the inductance L should be
connected to the cathode of the freewheeling diode via a conducting area/surface on the
PCB to avoid parasitric effects when being connected only through the conducting paths.
Pin 9 (FB), R
RST1, RRST2, the other terminal of L and the driven load RLOAD should be
directly connected to C
OUT and the GND-terminals of CIN1, CIN2 TLE 6387 and the
freewheeling diode should be star-connected to the GND terminal of C
OUT.
The line connecting pin 1 (GDRV) and the gate of the driven transistor as well as the
wires connecting C
BT should be as short as possible. CIN1 should be placed as close as
possible to the drain of the MOSFet and the path connecting pin 2 (V
S) and CIN1 should
be as short as possible.
In order to enhance cooling of the TLE 6387 which may be necessary when operating at
high ambient temperatures, any of its GND pins should be connected to a heatsink area.
