Application information
7.1
Reverse polarity protection
STCS05 must be protected from reverse connection of the supply voltage. Since the current
sunk from VCC pin is in the range of 450 µA a small diode connected to VCC is able to
protect the chip. Care must be taken for the whole application circuit, especially for the
LEDs, in fact, in case a negative voltage is applied between VIN and GND, a negative
voltage will be applied to the LED string that must have a total breakdown voltage higher
than the negative applied voltage in order to avoid any damage.
7.2
Thermal considerations
The STCS05 is able to control a LED current up to 500 mA and able to sustain a voltage on
the drain pin up to 40 V. Those operating conditions are however limited by thermal
constraints, the thermal resistances shown in the thermal data section is the typical ones.
The power dissipation in the device can be calculated as follow:
PD = (VDRAIN - VFB) x ILED + (VCC x ICC)
basing on this and on the thermal resistance and ambient temperature, the junction
temperature can be calculated as:
TJ = RthJA x PD + TA
A typical application could be:
– Input Voltage: 12 V;
– 3 white LEDs with an typical VF = 3.6 V;
– LEDs current: 350 mA;
–Package: SO-8;
–TA = 50 °C;
