buck boost converter

Hey, I´m currently trying to convert a 20kHz PWM Signal generated with an ESP32 to DC voltage. Goal is to control a hydraulic proportional flow control valve with a DRV103 solenoid Driver. The DRV103 needs an analog Input Signal from +2.2 - +5V to activate the Output. With the ESP I´m able to...

I'm a beginner electronics enthusiast. I'm working on a variable power supply made from an ATX PSU. For the variable voltage output, I'm planning on using a step up module from the 12V 16A ATX in, boost it up to 30V then connect that to the step down converter for variable voltage. Is this ok...

Hi guys, I designed a four switch buck boost converter with two UCC21520 gate driver ICs. When I supply the VCCI & VDDA of 5V and 12V to the gate drivers, there's a voltage output of around 2V in the output terminals. When an input voltage supply of 15V is connected, and PWM signals are provided...

I was trying to make a portable PSU with LTC3780 Module and a 12v 7Ah lead acid battery. But I am thoroughly disappointed by the module. Infact my past experience with this module is not good. This module is like a glass ball, with little improper use and it smokes and gets destroyed. I do not...

Hi, My requirement is that I have an input of 10VC to 32VDC and I have to design a power supply that can convert the said input to 12VDC with a capability of sustaining load of 310mA minimum. As i am looking for a cost effective solution it will require me to design a discreet buck boost...

Greetings, I am facing issue with TPS61240 as a buck-boost converter. I am using TP4056 to charge the battery and DW01 (and FS8205) to protect the battery by referring this blog. Also, note that I want to operate the other module; due to this I am using this below shown circuit to high/low...

I am trying to build a buckboost converter for converting 5-40v input to 5-35V output at 3A max to use it for many purposes by usign TL494. I am using a SEPIC topology as i want a non inverting output. I simulated the circuit in proteus. The circuit works fine when i connected a 500 Ohm load, I...

Hello all, Disclosure, I am an electrical engineer but I deal with designing power system for construction projects. I decided to go back for Masters in Power Electronics. I'm rusty with DC circuits. My homework is the same as a previous thread...
