The TNY280PG is a Step-Down Converter controller that\'s part of a power supply solution meant for offline conversion of a wide input voltage range. The key features include Low start up current, a Low Quiescent current, and a high efficiency over a broad input voltage range, while maintaining tight line and load regulations. It\'s also able to work with a wide variety of input sources, from AC (Alternating Current) to DC (Direct Current).

The working principle of the TNY280PG is based on Pulse-Width Modulation (PWM). It\'s able to produce a fixed frequency PWM output in response to the sensed voltage at its feedback pin, VFB. This output is then connected to a MOSFET (metal-oxide-semiconductor field-effect transistor) that serves as a switch to control the current flowing into a load. The MOSFET is switched at a fixed frequency and the duty cycle of the switch is adjusted such that the desired output voltage is achieved while maintaining the efficiency of the converter.

The TNY280PG can be used in a wide range of applications which include DC-DC converters, power supplies, battery chargers and DC motor controllers. In addition, its low starting current makes it suitable for applications such as portable consumer electronics. The TNY280PG is also compatible with a variety of sensing topologies, such as voltage mode, current mode and hysteretic mode control. This makes it a great solution for many offline applications requiring precise control over output voltage and current.

The TNY280PG has the flexibility to enable a wide variety of applications ranging from portable consumer electronics to other offline apps requiring precise control over the output voltage and current. Its low start up current and quiescent current make it suitable for applications such as battery chargers, DC-DC converters and many other offline solutions. Furthermore, its compatibility with a wide range of sensing topologies enables easy control of varied loads.
