Product Description
- DESCRIPTION
- The UCC28740 isolated-flyback power-supply controller provides Constant-Voltage (CV) using an optical coupler to improve transient response to large load steps. Constant-Current (CC) regulation is accomplished through Primary-side Regulation (PSR) techniques. This device processes information from opto-coupled feedback and an auxiliary flyback winding for precise high-performance control of
- output voltage and current.
- FEATURES
- • Less than 10-mW No-Load Power Capability
- • Opto-Coupled Feedback for CV, and Primary-Side Regulation (PSR) for CC
- • Enables ±1% Voltage Regulation and ±5% Current Regulation Across Line and Load
- • 700-V Startup Switch
- • 100-kHz Maximum Switching Frequency Enables High-Power-Density Charger Designs
- • Resonant-Ring Valley-Switching Operation for Highest Overall Efficiency
- • Frequency Dithering to Ease EMI Compliance
- • Clamped Gate-Drive Output for MOSFET
- • Overvoltage, Low-Line, and Overcurrent Protection Functions
- • SOIC-7 Package
- APPLICATIONS
- • USB-Compliant Adapters and Chargers for Consumer Electronics
- – Smart Phones
- – Tablet Computers
- – Cameras
- • Standby Supply for TV and Desktop
- • White Goods
