The FSDL0365R is a highly integrated power switch designed for offline power supplies. This device combines a SenseFET and a current mode PWM controller in a single package, reducing external components and simplifying design. It's specifically designed for applications requiring efficiency and a compact footprint.

Applications:

• Auxiliary power supplies for consumer electronics
• Adapters for various electronic devices
• Standby power supplies
• Open-frame power supplies

Features:

• Integrated SenseFET and PWM controller
• Low startup current
• Built-in soft-start function
• Pulse-by-pulse current limiting
• Over Voltage Protection (OVP) with auto-restart
• Over Load Protection (OLP) with auto-restart
• Thermal Shutdown (TSD) with auto-restart
• Frequency modulation for EMI reduction

Benefits:

• Reduced component count simplifies design and reduces BOM cost.
• Improved power efficiency for compact and energy-efficient designs.
• Enhanced system reliability with protection features.
• Minimized EMI emissions for compliance with regulations.
• Compact solution for space-constrained applications.

Additional Details:

The FSDL0365R utilizes a current mode PWM control scheme, providing inherent line voltage feed-forward for better stability. The integrated SenseFET reduces the need for external current sensing components, further simplifying the design process. The built-in soft-start function minimizes stress on the power components during startup. Auto-restart feature for OVP, OLP, and TSD protects the system without permanent shutdown in case of temporary fault. Frequency modulation helps to reduce EMI. This device comes in a TO-220F package.
