This is subject to the added requirement of discharging whatever external capacitance may be attached to these pins.

An alternate approach is the use of the shutdown circuitry of Pin 10 which has been improved to enhance the available shutdown options. Pin 10 should not be left floating as noise pickup could conceivably interrupt normal operation. Since long term stability cannot be measured on each device before shipment, this specification is an engineering estimate of average stability from lot to lot.

You can download the IR datasheet from the IR website. Now let's talk about the different pins.

VCC is the low-side supply and should be between 10V and 20V. VDD is the logic supply to the IR The actual voltage you choose to use depends on the voltage level of your input signals. This means that it can be used for almost all circuits, since most circuits tend to have around 5V outputs.

So, the IR can be easily used. VSS is the logic supply ground.

It seems that they are independent and you might think you could perhaps isolate the drive outputs and drive signals. The output to HO — high or low — is not with respect to ground, but with respect to VS. VS is the high side floating supply return.

The output on LO is with respect to ground. SD is used as shutdown control.

When this pin is low, IR is enabled — shutdown function is disabled. When this pin is high, the outputs are turned off, disabling the IR drive.

A large enough capacitance must be chosen for C1 so that it can supply the charge required to keep Q1 on for all the time. C1 must also not be too large that charging is too slow and the voltage level does not rise sufficiently to keep the MOSFET on.So we need to round off primary turns calculated value into nearest whole number 3.

In our design the output of dc to dc converter is volt at any input voltage. Since long term stability cannot be measured on each device before shipment, this specification is an engineering estimate of average stability from lot to lot.

With no load with fully charged battery, battery voltage will be near to Customers using or selling Vishay products not expressly indicated for use in such applications do so at their own risk. Vin here is the transformer secondary voltage. Such statements are not binding statements about the suitability of products for a particular application.

You look at the plant bode plot, pick a reasonable crossover frequency for the loop and work out how much gain and phase boost you need to stabilise and optimise the loop at that frequency put that into the equations and it will tell you where to put the poles and zeros around the crossover frequency to achieve this.
