The 5H0165R is a Fairchild/ON Semiconductor FPS™ Power Switch. It is an integrated off-line power switch with a Pulse Width Modulation (PWM) controller and a high-voltage power MOSFET. This device is designed for simple and efficient power supplies.

Applications:

• Power adapters
• Battery chargers
• Auxiliary power supplies
• Standby power supplies

Features:

• Integrated PWM controller and power MOSFET
• Low start-up current
• Built-in soft-start function
• Overload protection
• Overvoltage protection
• Thermal shutdown protection

Benefits:

• Reduces component count and simplifies power supply design.
• Ensures reliable operation with built-in protection features.
• Improves efficiency and reduces power consumption.
• Provides stable and regulated output voltage.

Additional Details:

The 5H0165R typically operates at a fixed switching frequency. It provides a high level of integration, reducing the need for external components. The built-in protection features prevent damage to the device and the power supply in case of overload, overvoltage, or overtemperature conditions. It is commonly used in cost-effective and compact power supply designs.
