Description

Description
The UCC28700 family of flyback power supply controllers provides Constant-Voltage (CV) and Constant-Current (CC) output regulation without the use of an optical coupler. The devices process information from the primary power switch and an auxiliary flyback winding for precise control of output voltage and current. Low start-up current, dynamically controlled operating states and a tailored modulation profile support very low standby power without sacrificing start-up time or output transient response.
Features
• < 30-mW No-Load Power for 5-Star Rating
• Primary-Side Regulation (PSR) Eliminates OptoCoupler
• ±5% Voltage and Current Regulation
• 130-kHz Maximum Switching Frequency Enables High-Power Density Charger Designs
• Quasi-Resonant Valley-Switching Operation for Highest Overall Efficiency
• Patent-Pending Frequency-Jitter Scheme to Ease EMI Compliance
• Wide VDD Range Allows Small Bias Capacitor
• Clamped Gate-Drive Output for MOSFET
• Protection Functions: Overvoltage, Low-Line, and Overcurrent
• Programmable Cable Compensation (UCC28700 Only)
• NTC Resistor Interface (UCC28701, UCC28702 and UCC28703 Only) With Fixed Cable Compensation Options
• SOT-23 Package
