The recommended operating voltage range for the KA358D is 3.5V to 30V, although it can tolerate up to 35V for short periods.
To ensure stable operation in high-temperature environments, it's essential to provide adequate heat sinking and keep the junction temperature (Tj) below 150°C. A thermal pad or heat sink can help dissipate heat.
The maximum output current capability of the KA358D is 3A, but it's recommended to limit the output current to 2A for reliable operation and to prevent overheating.
To protect the KA358D from input voltage transients and spikes, it's recommended to add a voltage transient suppressor (TVS) or a zener diode in parallel with the input capacitor to clamp the voltage.
The bootstrap capacitor is used to generate a voltage higher than the input voltage to drive the high-side switch. It's essential for proper operation and should be selected based on the input voltage and switching frequency.
