LT3511 5 volts switching power supply circuit diagram project

A very simple 5 volts switching power supply electronic project can be designed using the LT3511 high voltage monolithic switching regulator manufactured by Linear Technology , specifically designed for the isolated flyback topology.
No third winding or opto-isolator is required for regulation as the part senses output voltage directly from the primary-side flyback waveform. The device integrates a
240mA, 150V power switch, high voltage circuitry, and control into a high voltage 16-lead MSOP package with four leads removed.
This simple 5 volts switching power supply based on the LT3511 operates from an input voltage range of 36V to 72V and delivers up to 1.5W of isolated output power.
Two external resistors and the transformer turns ratio easily set the output voltage.
The high level of integration and the use of boundary mode operation results in a simple, clean, tightly regulated application solution to the traditionally tough problem of isolated power delivery.

This simple 5 volts switching power supply based on the LT3511 will provide a fixed output voltage of 5 volts at a maximum output current of 300mA .
As you can see in the circuit diagram , this electronic project , require few external electronic parts and can be used in applications like : isolated telecom power supplies , isolated auxiliary/housekeeping power supplies , automotive and medical power supplies .
The LT3511 operates similar to traditional current mode switchers, except in the use of a unique error amplifier, which derives its feedback information from the flyback pulse. The diode needs to handle the peak switch current of the switch , you can use the following diodes type D1: DIODES INC. SBR140S3 D3: DIODES INC. BAV19W and Z1: ON SEMI MMSZ5266BT1G .
T1 transformer must be a WÜRTH 750311558 type .
