Working Principle

The INN3168C-H101-TL performs offline AC-DC conversion using a high-performance, high-efficiency flyback topology. It integrates a full-bridge rectifier, a wide 2:1 input voltage range, low-profile components, and optimized feedback and control circuitry to quickly achieve low-output voltage and high-efficiency. The integrated control and power FETs combine two power switches into a single unit, which reduces parasitics and optimizes the power delivered from the input source to the output. The integrated PFC (Power Factor Correction) circuit limits the inrush current of the power supply during the start-up process and ensures smooth, complete operation. The OTP (Over Temperature Protection) circuit monitors and protects the IC from damage due to excessive temperature. The compact size (15.5*20.5*5.0mm) allows it to fit into tight spaces, making it ideal for space-constrained applications.

In sum, the INN3168C-H101-TL offers a wide range of features and benefits, making it an ideal solution for high-efficiency or low-power applications. It has a wide AC input voltage range, excellent no-load power consumption, high-efficiency, and an integrated control and power FET. The OTP circuit further ensures safe and reliable operation. Additionally, its compact size saves PCB space and allows it to fit into compact applications.
