The maximum operating frequency of the STW9N150 is 150 kHz, but it can be operated up to 200 kHz with some derating of the output power.
To ensure the stability of the output voltage, it is recommended to use a minimum output capacitance of 10uF and to keep the output voltage sensing lines as short as possible to minimize noise and oscillations.
The maximum input voltage that the STW9N150 can handle is 28V, but it is recommended to operate it within the specified input voltage range of 8-18V for optimal performance and reliability.
The STW9N150 has built-in overcurrent protection and thermal shutdown features. However, it is recommended to add external protection circuits, such as fuses or PTC resistors, to prevent damage from excessive current or temperature.
The STW9N150 is rated for operation up to 150°C, but its performance and reliability may degrade at high temperatures. It is recommended to derate the output power and ensure good thermal management to prevent overheating.
