TNY176PN Pinout Equivalent

1：Overview of the TNY176PN：

TNY176PN is a high-performance monolithic switching power supply integrated circuit launched by Power Integrations. It adopts an 8-pin dual in-line package (DIP-8) form. This chip integrates a PWM controller and a power MOSFET on the same chip, with high integration, which can effectively simplify the design of switching power supplies and reduce the area of circuit boards. TNY176PN has overvoltage, overcurrent, and overheating protection functions and can automatically cut off the output under abnormal conditions to ensure the safe and stable operation of the circuit. It has high working efficiency and can maintain good performance within a wide input voltage range (85VAC to 265VAC). It can achieve low standby power consumption and is suitable for various application scenarios that require low power and high-efficiency power supplies, such as chargers, adapters, and auxiliary power supplies.

3: Alternative Modellempfehlung

TNY276PN：Belongs to the TinySwitch-III series of Power Integrations. It has a DIP-8 package (with actually 7 effective pins). 2. The operating temperature range and input voltage range are similar to those of TNY176PN. The output voltage is 12V. The frequency range is 124 – 140kHz. It integrates a 700V power MOSFET, oscillator, etc. 2. Its power is greater than that of TNY176PN. In some occasions where the power requirement is not particularly strict and its electrical characteristics can be adapted, it can be used as a replacement.

TNY280PN：TinySwitch-III series, DIP-7 package. This chip has a relatively large power. If the original circuit can adapt to its power and electrical characteristic changes, it can be used to replace TNY176PN. However, it should be noted that TNY176PN has a small power. If it is used in the circuit of TNY280PN, it may not be able to normally drive a large load.

NCP1014：It is also a switching power supply controller integrated with a high-voltage MOSFET and can be used for off-line switching power supply applications. It is similar in function to TNY280PN and can both achieve efficient power conversion.

LNK306PN：As a product of Power Integrations, it has overlapping functions with TNY280PN. Both can achieve the basic functions of switching power supplies and are suitable for low-power power supply applications.It adopts different control strategies and may require certain modifications to the circuit to achieve substitution.
