HC7703B Synchronous Rectifier IC, Number of Pins: 8

HC7703B is a high-performance synchronous rectifier IC designed to replace traditional diode rectifiers on the secondary side of flyback converters. By emulating diode rectification with an integrated power MOSFET, it significantly reduces conduction losses and enhances overall system efficiency. This IC supports multiple operating modes including Discontinuous Conduction Mode (DCM) and Quasi-Resonant (QR) mode, making it highly versatile for modern power supply designs. With high integration, HC7703B reduces the need for external components, simplifies PCB layout, and lowers total BOM cost-ideal for compact and efficient power solutions. Key Features: Supports DCM & QR Flyback Converter Applications Integrated 40V, 16mΩ Power NMOS Green Mode Operation for light load and no-load conditions Improves overall power efficiency Reduces conduction losses Operates up to 100kHz switching frequency Highly integrated design for minimal external components Available in SOP-8 package Technical Specifications: Product Name: HC7703B Synchronous Rectifier IC Voltage Rating: 40V On-Resistance (RDS(on)): 16mΩ Switching Frequency: Up to 100kHz Operating Modes: DCM, QR Mode Package Type: SOP-8 Application Type: Secondary side rectification Applications: Travel Chargers Power Adapters Flyback Converters Mobile Chargers SMPS Power Supplies Benefits: Higher efficiency compared to diode rectifiers Lower heat generation Compact and cost-effective design Reliable performance in modern power electronics Minimum Order Quantity (MOQ): 4000 Pieces About the Company GST Registration Date: Jul 2017 Legal Status of Firm: Proprietorship Number of Employees: 26 To 50 People Annual Turnover: 25 - 100 Cr company-description: DDS International - Edzeal is India's trusted online destination for sourcing high-quality electronic components and switches for industrial and OEM applications.
