Dear Takeshi-san,
thanks for your reply.
Would give me the ciruict that you have suggested? i dont not have idea..
please provide me that circuit , with all specified value of components . thanks
Hi,
thanks for reply,
Yes, I have only one coil. Transformer has only one secondary whcih is giviing me 19V AC . I can not change the transfomer . Already +24V is generated through rectification.
regulation is not necessary. Little variationis accepted on -24V line .
How to generate -24V @...
Hi All,
I have 19V AC coming out of transformer , which i am rectifying and generating +24V dc out put.
I wanted to have -24V at same time as another output ?
But -24V could be maximum of 1A load.
How to get -24v from +24V or present +19V AC ?
Is there any ready made module from any...
Hi All,
Anyone know about power supply and analog consultant at Bangalore , Inida ? I am working in a company situated in bangalore , majorly working on Hardware domain. We are looking for a professional consultant in power supply and analog domain , in whcih consultant should helps us in...
Hi I am using dual N channel and P channel Mosfet for one of my switching application. The part number is IRF7317PBF. The Mosfet is a SO-8 Package.
The pchannel mosfet works fine. But problem is with n channel . Input to the N channel is 5v . and the Gate drive for n channel is 4.5v. So N...
hi
I have an application, which requires specification like below.
Input voltage range = 21v to 61v (dc)
Output voltage = 12v @ 10A ( 120W system)
Type: Non- Isolated / Isolated
I am looking for power supply module for above 120W . ( DC to DC module)
Can anybody suggest readymade power...
low power pwm
Hi
I need to generate PWM signal for battery powered application to make ON/OFF for a swicth.The frequency is typically 1 second and I need to have a variable duty cycle by means of POT. I did look into 555 and 556 timer circuts and op amp PWM geneartion cicuits . It looks they...
mosfet gate drive
Hi AdrianN,
thanks for your suggestion. To keep MOSFETs parallel , i have got space problem. and i am not allowed to make both side placement. :(
So i may not be able to do it. I need to check with series resistor with Gate. DO you think , increase in Gate capacitance is the...
mosfet gate driver
Hi All
I am using LTC3810 in one of my application.
As given in the datasheet ,I used Si7852 / Si7174 MOSFETs as TOP and BOTTOM Mosfets.
My Input is 24V ( range is 21v to 62v)and Out put is 12v @ 3A and switching frequency is 250Khz. This gives us duty cycle of 50% at...
boost converter calculation
Hi
Anybody having step by step procedure to calculate Synchronous & Asynchronous Boost converter efficiency ? Please share if you have.
thanks in advance
