Introduction to LT3750

Hello readers welcome to new post. Today we will learn Introduction to LT3750. It device is used for charging the high volts capacitors with high speed with use of less exterior elements. It is named as a current mode flyback converter.

In this post, we will learn its pinout working features and some other paramrets. So let get started Introduction to LT3750

Table of Contents

The LT3750 is a flyback converter created for high-speed sharing of larger capacitors for required volts.

It has less value of transition losses and decreases the size of the transformer since has a patented boundary.
Turn ration of transformer and 2 exterior resistance changes the value of output volts.
The small value of current about seventy-eight millivolts detects correctly limits peak current and enhances the efficiency.
It has different values of input voltage ranges so it can work on different power supplies
It has the ability to charge the one hundred microFarad capacitor in just three hundred milliseconds for three hundred volts
its charging pinout can give complete control to the users. Its DONE pin used to indicate the charging of the capacitor

LT3750 Features

The main features are discussed here
It comes in MS packaging having ten leads
It can drive the MOSFET gate at minus two volts Vcc
It can operate at different values of input volts from three volts to twenty-four volts
It not need any output voltage divider
It can operate high current use NOMS field effect transistors
Its output volts can be regulated easily
It has the ability to charge any capacitance value of charge

LT3750 Pinout

The main pinout of LT3750 are explained here

Pin 1 Transformer Supply Pin. Powers the primary coil of the transformer as well as internal circuitry that performs boundary mode detection. Bypass at the pin with a 1µF to 10µF capacitor. Bypass the primary winding of the transformer with a large capacitor
Pin 2 is DONE used for configuring the completion of a single cycle of charging
Pin 3 its high configuration indicates the charging initiating.
Pin 4 is use to get the power supply
Pin 5 is ground
Pin 6 It is linked to the source pin of MOSFET and also has a connection to current sensing resistances
Pin 7 is used for the gate of MOSFET
Pin 8 It used for the detection of boundary mode to start new switching cycle
Pin 9 Used to transform the reflected secondary volts to current
Pin 10 transforms the current get through pin 9 in the volts that sensed by the comparator to stop the charging process
