VIPER53SPTR-E Frequently Asked Questions (FAQ)
-
STMicroelectronics recommends a 4-layer PCB with a solid ground plane, and a separate layer for the high-voltage power supply. The layout should also minimize the loop area of the high-frequency circuits to reduce EMI.
-
To ensure reliable start-up, ensure that the input voltage rises slowly (dv/dt < 50 V/ms) and the input capacitor is properly sized to filter out voltage spikes. Also, add a soft-start circuit to limit the inrush current.
-
The maximum allowed voltage drop across the internal switch is 1.5 V. Exceeding this limit may reduce the device's reliability and lifespan.
-
Use an overvoltage protection (OVP) circuit to limit the input voltage to 38 V, and an undervoltage lockout (UVLO) circuit to prevent the device from operating below 8 V.
-
Use a heat sink with a thermal resistance of < 10°C/W, and ensure good airflow around the device. Also, consider using a thermal interface material (TIM) to improve heat transfer.
