Description

The TNY290PG is a member of Power Integrations’ TinySwitch-III series, designed for low-power off-line switch-mode power supplies (SMPS). This IC integrates a high-voltage power MOSFET, oscillator, high-voltage switched current source, current limit, and thermal shutdown circuitry into a single, compact package. The TNY290PG is ideal for applications that require high efficiency, reliability, and a compact design.

Features

  • Integrated High-Voltage MOSFET: Combines a 700V power MOSFET with control circuitry, which simplifies the design and reduces the number of external components.
  • TinySwitch-III Technology: Provides advanced features such as auto-restart, frequency jittering, and high efficiency, making it suitable for modern, energy-efficient power supply designs.
  • Low Standby Power: Designed for very low standby power consumption, ideal for applications needing to meet stringent energy efficiency standards.
  • High Efficiency: Ensures high efficiency across a broad range of load conditions, minimizing power loss and heat generation.
  • Auto-Restart Protection: Features auto-restart functionality to protect against output short circuits and open-loop conditions, enhancing reliability and safety.
  • Frequency Jittering: Helps reduce electromagnetic interference (EMI) by varying the switching frequency, making it easier to comply with EMI regulations.
  • Thermal Shutdown: Includes thermal shutdown protection to prevent overheating, ensuring reliable operation in various conditions.

Specifications

  • Input Voltage Range: 85V to 265V AC
  • Output Power:
    • Up to 40W in open frame designs
    • Up to 25W in enclosed adapters
  • Switching Frequency: 132 kHz with frequency jittering
  • MOSFET Breakdown Voltage: 700V
  • Current Limiting: Integrated cycle-by-cycle current limiting for robust protection
  • Standby Power Consumption: <50mW at 265V AC input
  • Efficiency: Typically greater than 80%
  • Operating Temperature Range: -40°C to +150°C (junction temperature)
  • Package: 8-pin PDIP (Plastic Dual In-line Package)

Applications

  • AC-DC adapters for consumer electronics, including mobile devices, small appliances, and laptops
  • Standby power supplies for TVs, monitors, and other home electronics
