Isolated 24V to 12V 10W Flayback Power Supply System Diagram using TGSP-P145EP10LF

Robometricschool. - This is one of the application of TGSP-P145EP10LF to build isolated 24V to 12V 10W flayback power supply for you. As you know that Isolated power supplies provide reliable power regulation for a variety of applications. 

In here we will give you the system diagram of Isolated 24V to 12V 10W Flayback Power Supply using TGSP-P145EP10LF and then also you can read the global description of this design.

Accordingly Maximintegrated site that published this project describe that Multiple transformers (Halo Electronics TGSP-P145EP10LF, Wurth Electronics 750315882, HanRun HR051075, and Sumida 12387T070) have been qualified for this design, simplifying the process of transformer selection. In addition, through-hole pins on the bottom side of the module allows quick and easy integration of this power converter into the main system. Pins are 0.6in from power to ground, and 2in from the input side to the output side.

The MAX17596 is a peak-current-mode controller for design of wide input-voltage flyback and boost regulators. The reference design operates over a 17V to 36V input voltage range, and provides up to 800mA (plus 20% overhead) at 12V output. The MAX17596 has an internal amplifier with 1% accurate reference, eliminating the need for an external reference. The switching frequency is programmable from 100kHz to 1MHz with an accuracy of 8%, allowing optimization of magnetic and filter components, resulting in compact and cost-effective power conversion. This design is set to switch at 500kHz. For EMI-sensitive applications, the MAX17596 incorporates a programmable frequency dithering scheme, enabling low-EMI spread-spectrum operation.
