TNY256G General Description

The TNY256 extends the power range of the TinySwitch family of energy efficient, low power off-line switchers. TinySwitch devices use a breakthrough design to provide the lowest cost, high efficiency, off-line switching solution for low power applications. They integrate a 700 V power MOSFET, oscillator, high voltage switched current source, current limit and thermal shutdown circuitry into a single, monolithic device. The devices start-up and operate on power derived from the DRAIN voltage, eliminating the need for a transformer bias winding and associated circuitry. TinySwitch's low operating current allows power supply no-load consumption to be kept under 100 mW, even at 265 VAC input.

The TinySwitch Plus incorporates auto-restart, line under-voltage sense, and frequency jittering features. The auto-restart circuit safely limits output power during fault conditions such as output short or open loop. The auto-restart circuit is fully integrated and does not require external timing components. The line undervoltage sense threshold can be externally programmed using a line sense resistor. During start-up, this feature keeps the TNY256 off until the input line voltage reaches the under-voltage threshold. When the input line voltage is removed, the line under-voltage circuit prevents auto-restart attempts after the output goes out of regulation. This eliminates power down glitches caused by the slow discharge of input storage capacitors present in applications such as standby supplies. A single resistor is used to implement this feature, eliminating what normally takes five to six components. The line sense resistor is optional. The TNY256 operating frequency of 130 kHz is jittered (frequency modulated) to reduce both quasipeak and average EMI, minimizing filtering costs.
