Description

Electronic Component Model TNY263GN is an offline switcher belonging to the product category of AC DC Converters. It is an enhanced, energy-efficient, low power electronic component. This model integrates a 700 V power MOSFET, oscillator, high voltage switched current source, current limit, and thermal shutdown circuitry on a single chip. TNY263GN eliminates the need for a bias winding and associated circuitry by deriving start-up and operating power directly from the voltage on the DRAIN pin. It also incorporates auto-restart, line under voltage sense, and frequency jittering. Audio frequency components are minimized, practically eliminating audible noise with standard taped/varnished transformer construction.

Specifications and Features

TinySwitch-IIFeatures Reduce System Cost
• Fully integrated auto-restart for short circuit and open loop fault protection – saves external component costs
• Built-in circuitry practically eliminates audible noise with ordinary dip- varnished transformer
• Programmable line under-voltage detect feature prevents power on/off glitches – saves external components
• Frequency jittering dramatically reduces EMI (~10 dB) – minimizes EMI filter component costs
• 132 kHz operation reduces transformer size – allows the use of EF12.6 or EE13 cores for low cost and small size
• Very tight tolerances and negligible temperature variation on key parameters ease design and lowers cost
• Lowest component count switcher solution
• Expanded scalable device family for low system cost

Application Scenarios

Since TNY263GN reduces system cost with low power, enhanced, and energy-efficient performance, it is best suited for electronic devices used in applications of AC DC converters, offline switchers, and other related applications.
