NCP1547DR2G Frequently Asked Questions (FAQ)
-
The recommended PCB layout for optimal thermal performance involves placing the device on a thermal pad connected to a large copper area on the PCB, and ensuring good airflow around the device. A minimum of 2oz copper thickness is recommended for the thermal pad.
-
To ensure reliable start-up of the device in a high-noise environment, it is recommended to add a capacitor (e.g. 10nF) between the VIN pin and GND, and to use a low-pass filter on the EN pin to filter out noise.
-
The maximum allowed voltage on the EN pin is 6V, exceeding which may cause damage to the device. It is recommended to use a voltage divider or a clamp circuit to limit the voltage on the EN pin.
-
The output voltage ripple of the device can be calculated using the formula: ΔVout = (Iout * Rds(on) * fsw) / (Cout * Vout), where Iout is the output current, Rds(on) is the on-resistance of the internal FET, fsw is the switching frequency, Cout is the output capacitance, and Vout is the output voltage.
-
The recommended input capacitor type is a low-ESR ceramic capacitor (e.g. X5R or X7R) with a value of 10uF to 22uF. The capacitor should be placed as close as possible to the VIN pin.
