SC1545CS-1.8TRT Frequently Asked Questions (FAQ)
-
A good PCB layout for SC1545CS-1.8TRT involves keeping the input and output traces short and symmetrical, using a solid ground plane, and placing decoupling capacitors close to the device. A 4-layer PCB with a dedicated power plane and a separate ground plane is recommended.
-
To ensure proper biasing, connect the VCC pin to a stable 1.8V power supply, and decouple it with a 10uF capacitor. The EN pin should be tied to VCC or a digital signal to enable the device. The VIN pin should be connected to a stable input voltage source, and the VOUT pin should be decoupled with a 10uF capacitor.
-
The maximum input voltage that can be applied to the SC1545CS-1.8TRT is 5.5V. Exceeding this voltage may damage the device.
-
The output voltage of the SC1545CS-1.8TRT is fixed at 1.8V. However, if you need to calculate the output voltage for a custom design, you can use the formula: VOUT = (VIN x (R1/R2)) + VREF, where R1 and R2 are the feedback resistors, and VREF is the internal reference voltage.
-
The thermal derating of the SC1545CS-1.8TRT is typically 1.5°C/W above 25°C. This means that for every 1°C increase in ambient temperature above 25°C, the device's power rating decreases by 1.5%.
