Description

The TinySwitch family is the newest generation of Power Integrations’ industry-leading TinySwitch series of off-line switcher ICs. An off-line regulator is essentially a fully working integrated circuit. This gadget is required to guarantee that a tiny portable or handheld device receives clean electricity.

TinySwitch-TNY278PN is a single-chip device that combines a high-voltage power MOSFET switch with a power supply controller. An oscillator, enable circuit (sense and logic), current limit state machine, 5.85 V regulator, BYPASS/MULTI-FUNCTION pin, Undervoltage, overvoltage, and current limit selection circuitry, over-temperature protection, current limit circuit, leading-edge blanking, and a 700 V power MOSFET are all included in the controller. The ON/OFF control technique is used by the IC family. As a result, it provides a design-friendly solution with a reduced system cost and increased power capabilities. It regulates the output voltage using a simple ON/OFF control, unlike traditional PWM (pulse width modulator) controllers.

An off-line regulator is a comprehensive integrated circuit that includes all of the functions required to provide clean power to a tiny portable or handheld device. Alternatively, it can be utilized as part of a bigger SMPS or DC-DC converter. It also has a line-compensated excessive power protection system. As a result, across the full AC input voltage range, these devices drastically decrease the maximum overload power that may be given to the load. For high reflected voltage and high bus-voltage systems, the 700 V MOSFET simply allows for 80 percent de-rating. Meanwhile, with 5% load, it has an efficiency of more than 70%. As a result, designers are able to satisfy the demanding European standard specification requirements.
