TNY267 Power management Chip

Description: The TNY267 is a member of the TinySwitch-III family of power management ICs designed for offline low-power applications. It integrates a high-voltage power MOSFET, oscillator, high-voltage switched current source, current limit, thermal shutdown protection, and other control circuitry onto a monolithic device. The IC operates in a flyback topology to provide highly efficient power conversion with minimal external components.

Key Features:

• Integrated high-voltage power MOSFET
• Integrated oscillator and switched current source
• Low component count design
• Auto-restart for fault protection
• Frequency jittering for low EMI
• Built-in line undervoltage lockout (UVLO)
• Thermal shutdown protection
• EcoSmart™ technology for low standby power consumption

Technical Specifications:

• Input Voltage Range: 85VAC to 265VAC
• Maximum Output Power: Up to 25W (depending on application and thermal conditions)
• Efficiency: Up to 86% (typical)
• Operating Frequency: 132 kHz (typical)
• Thermal Shutdown Temperature: 140°C (typical)
• Package Type: 7-pin DIP, 7-pin SOP

Applications:

• AC-DC power supplies
• Offline flyback converters
• Chargers and adapters
• Auxiliary and standby power supplies
