The LT3512EMS#PBF from Linear Technology is a high-performance, isolated monolithic flyback regulator that simplifies the design of an isolated DC/DC converter. With no third winding or opto-isolator required for regulation, the LT3512 features a primary-side sensing and feedback which directly controls the output voltage. This innovative design enables users to create a compact, efficient, and reliable power solution with ease.

Key Features

• Wide Input Voltage Range: The device operates over a 4.5V to 100V input voltage range, making it suitable for a variety of applications, including industrial, automotive, and telecommunications.
• Integrated 420mA, 150V Power Switch: Its robust built-in power switch enables it to handle high power applications with minimal external components.
• Programmable Soft-Start Function: This feature allows for the gradual increase of the output voltage, which helps prevent inrush current during startup.
• No Transformer Third Winding or Opto-Isolator Required: Simplifies design and improves reliability by using primary-side feedback for output voltage regulation.
• Boundary Mode Operation: The LT3512 operates in boundary mode, which is a variable frequency current mode control switching scheme, resulting in a smaller magnetic solution and improved load regulation.
