The TNY287PG is one of the most popular components used in power management integrated circuit (PMIC) applications. Its primary purpose is to convert alternating current (AC) voltage to direct current (DC) voltage and vice versa. It has a wide range of applications including off-line switcher applications and battery management systems. This article will discuss the application fields and working principles of the TNY287PG PMIC.The TNY287PG is a two-level resonance converter and a soft-start controller with internal power-MOSFETs. It is capable of operating in both discontinuous conduction mode (DCM) and continuous conduction mode (CCM). It is designed to be a reliable, low cost solution for AC-DC or DC-AC conversion applications.The TNY287PG can be used in both offline switcher and battery management applications. In offline switcher applications, the TNY287PG will be used to convert AC voltage to a higher or lower DC voltage as required. It is also used to rectify and invert direct current to AC voltage. In battery management applications, the TNY287PG is used to switch between different battery types and to convert AC to DC for battery charging.The main components of the TNY287PG include two power MOSFETs, an output diode, inductors and capacitors, a resistor, and a control IC. The TNY287PG is designed to have a wide input voltage range, which makes it suitable for use in both AC and DC voltage applications.In terms of working principles, the TNY287PG is designed to be a two-level resonance converter, which uses both level and frequency control techniques. The objective of the two-level architecture is to achieve a high power efficiency and a high conversion rate. In terms of frequency control, the TNY287PG is capable of switching between the two levels at different frequencies, thus allowing it to achieve a high frequency response and smooth operation. In terms of output voltage, the TNY287PG has an adjustable output voltage range that can be adjusted by setting the appropriate gain and switching frequency levels. This is done by adjusting three different resistors in the configuration.The TNY287PG has two different types of protections- current limit protection (CLP) and over-voltage protection (OVP). CLP ensures that the current does not exceed a certain level and OVP prevents the circuit from outputting more than a determined voltage level.Finally, the TNY287PG has a soft-start controller enabling the module to start operation without any disruption. This feature allows the device to quickly start-up and reach its required operation quickly.To conclude, the TNY287PG is a widely used and trusted power management IC used for AC-DC and DC-AC conversion applications. It has a wide input voltage range, allowing it to be compatible with both AC and DC systems. It also provides efficient and easily adjustable output voltage range. Finally, it also provides protection through current limit protection and overvoltage protection, while providing a soft-start feature to ensure fast start-up operation. The versatile and dependable TNY287PG is an ideal choice for a variety of applications in the power management integrated circuit field.
