About the Product

TNY284DG – Off-Line Switcher IC with Integrated 725V MOSFET for Energy-Efficient ASIC Miner Power Supply Units

The TNY284DG is a highly integrated off-line switcher IC designed for cost-effective, energy-efficient power conversion in AC-DC applications. Featuring an advanced TinySwitch-II family architecture, it combines a high-voltage 725V power MOSFET, oscillator, high-voltage switching control, current limit, and thermal shutdown circuitry in a compact SOIC-8 surface-mount package.

Engineered for power supply units (PSUs) used in ASIC miners, industrial electronics, and consumer devices, the TNY284DG delivers reliable performance with reduced component count, enhanced safety, and excellent thermal efficiency.

Its integrated start-up and current-limiting circuitry eliminates the need for external components, reducing PCB space and improving reliability in high-demand environments such as Whatsminer and Antminer PSU repairs.
