## LTC3780 for MPPT solar charger poblems

Hi there, I have some problems using LTC3780 for charging an lead-acid battery. I did manage to make a working buck-boost power supply with LTC3780 using the schematic form datasheet(for tests I managed to get 12,7V at 48W from 7-18V supply), but having it charging a battery from PV(power supply simulated) module failed. The symptoms are: (...)

## Buck Controller not working.

Apart from circuit details - there are more dubious points - the exact behaviour of the boost converter part can be only guessed without a simulation. For the time beeing I'll assume that it's working somehow. But how's the efficiency, does it use a reasonable operation point of the solar panel? How about in- and output voltages and currents wi

## Voltage converter for positive to negative voltage

A buck-boost converter can convert a positive supply to negative. schematic showing the basic You will need to add control circuitry. The .5 ohm resistor is a 'token' value added to represent some amount of

## how to design buck-boost converter?

i want to design +3 to 24V DC input voltage to fixed +5V DC using buck-boost. I don't have knowledge about that. Please refer some good notes with simple explanation and please help me how to design this? Thanks in advance :)

## Output current of bidirectional DC DC Converter

The schematic ist correct, it's a pretty standard buck-boost converter. You'll need to implement a current controller that sets the PWM duty cycle to operate the converter with defined output current. Of course the controller must be fast enough to keep up with the dI/dt rate defined by the inductor. Overcurrent shutdown triggered by IGBT (...)

## Buck-boost converter (DC/DC)

Hi all, I'm working on a buck-boost converter (DC/DC), the specifications are: for 0.5V in the input I must have 3v in the output, and for the amplitude of oscillations that excite the grid of the transistor NMOS it must be less than 3v (the output voltage). My problem is that when I give to the amplitude of oscillations 2.5v (that exite the grid

## Clamping MOSFET voltage using snubbers (TVS)

Dear Cheers Hi where is your schematic? there are more arrangement of buck boost converter available . Best Wishes Goldsmith

## Need help for SMPS 0-450V 200mA

but he need it in buck/boost design from 0-430v

## a dc to dc converter problem

Could you write some others details about the converter e.g. topology (buck, boost, ...), feedback type (voltage mode, current mode, ...), functioning mode (CCM, DCM, ...), voltage on input/output and so on... Do you've some circuit schematic? Bye

## Buck-Boost: Vout=-10V, Iout=20mA ???

I'm on project about buck-boost regulator. I've just reached Vout=-7V.I need Vout=-10V, Iout=20mA. Anyone can help me? Regards!

## Using 8051 to control Buck regulator, Boost regulator

I need a schematic about buck regulator, boost regulator, LDO regulator and code (*.asm, *.v). Who can help me? Thanks! With best regard. :cry::cry::cry::cry::cry::cry::cry::cry::cry::cry::cry::cry::cry::cry::cry::cry::cry:

## Help me design a uC controlled buck/boost converter

I'm looking to use an atmel attiny uC to make a simple yet efficient (85%) and SMALL buck/boost converter. boost from around 1.8V and buck from 6-9V to drive a luxeon led. I need a schematic to get started and i'll figure out the writing of the code. Please help! Thanks!
