Requirement of DC-DC converter

[prakash1]

Hi ST team,

 

I have requirement of DC-DC converter as per below :-

1. Input voltage range: 20V-30V/1A
   Required dual output  +15V and -15V.
   
   
2. Input voltage range:  20V-30V/1A
   Required dual output +10V and -10V.
   
   
3. Input voltage range : 20V-30V/1A
   Required output voltage: +5V only
   
   
4. LDO for controller: Input voltage 5V and Output voltage 3.3V

Kindly suggest for the same.

If these are to be four different applications and therefore independent converters, only flyback converters should be considered for 1 and 2 due to the dual outputs. However, it is not usually the input current of the converters that is specified, but the output current.

The output current is also missing for request 4. Could you please specify the currents for the individual output voltages?

BTW: do you know our Online Design and Simulation tool eDesignSuite? Just click on Power Supply Design Tool > DC/DC and Start Design.
