TEXAS INSTRUMENTS UC2577TDKTTT-ADJ 芯片, 直流/直流转换器
DESCRIPON
The UC2577-ADJ device provides all the active functions necessary to implement step-up boost, flyback, and forward converter switching regulators. Requiring only a few components, these simple regulators efficiently provide up to 60V as a step-up regulator, and even higher voltages as a flyback or forward converter regulator.
FEATURES
• Requires Few External Components
• NPN Output Switches 3.0A, 65Vmax
• Extended Input Voltage Range: 3.0V to 40V
• Current Mode Operation for Improved Transient Response, Line Regulation, and Current Limiting
• Soft Start Function Provides Controlled Startup
• 52kHz Internal Oscillator
• Output Switch Protected by Current Limit, Undervoltage Lockout and Thermal Shutdown
• Improved Replacement for LM2577-ADJ Series
TYPICAL APPLICATIONS
• Simple Boost and Flyback Converters
• SEPIC Topology Permits Input Voltage to be Higher or Lower than Output Voltage
• Transformer Coupled Forward Regulators
• Multiple Output Designs
