Sample Application Circuit
Notes on Usage
1. External diodes
Because this IC uses top-side transistor switching in SLOW DECAY mode and dual-side transistor switching in FAST DECAY
mode, it requires external diodes between the OUT pins and ground, for the regenerative current during switching OFF. Use Schottky
barrier diodes with low VF.
2. V
REF
pin
Because the V
REF
pin serves for input of the set current reference voltage, precautions against noise must be taken. The input voltage
range is 0 to 3.0V.
3. GND pin
The ground circuit for this IC must be designed so as to allow for high-current switching. Blocks where high current flows must use
low-impedance patterns and must be removed from small-signal lines. Especially the ground connection for the sensing resistor RE
at pin E, and the ground connection for the Schottky barrier diodes should be in close proximity to the IC ground.
The capacitors between V
CC
and ground, and V
BB
and ground should be placed close to the V
CC
and V
BB
pins, respectively.
