RVPW011-FJ1-R Coming Soon

RVPW011 is a flyback converter that achieves voltage regulation by sampling the primary winding of the transformer, supporting primary-side regulation (PSR) feedback at operating frequencies in the hundreds of kHz. Its internal output voltage sampling circuit operates with a sampling voltage pulse as narrow as 400ns. Equipped with an internal loop compensation circuit and fast dynamic response capability, the RVPW011 ensures excellent system stability and dynamic performance for switching power supplies. Designed for low-voltage operation, the RVPW011 supports input voltages as low as 5V. It features a low on-resistance internal MOSFET of just 40mΩ. Combined with its thermally efficient 5mm×5mm QFN package, the device can deliver output power up to 30W. RVPW011 integrates multiple control functions with minimal external components, allowing designers to tailor the system to specific application needs. It enables startup, feedforward compensation, and control over the shutdown speed of the internal power MOSFET via external resistors. The peak current of the power MOSFET can also be programmed using a resistor, enabling “lossless” current sensing. Input undervoltage and overvoltage protection thresholds can be set simultaneously using two resistors. Additionally, the soft-start time is programmable through an external capacitor, allowing for optimized performance based on the application. To ensure robust and reliable operation, the RVPW011 incorporates built-in protections including overload protection, output short-circuit protection, output overvoltage protection, and over-temperature protection. These protection mechanisms support automatic recovery after fault conditions are resolved, maximizing the reliability and resilience of the overall power supply system.
