In this post we are going to learn how we can make one real working smart solar battery charger circuit which can do MPPT charging. We are using Arduino Nano as the brain for controlling everything. We will also use INA219 sensor module so that we can read the solar voltage and current properly. And […]

SMPS Flyback Boost Converter Calculator
This calculator tool supports a Boost Converter Flyback setup which means now the code considers: Corrected turns ratio and primary voltage logic since the flyback works by storing energy during “ON” time and transferring to secondary during “OFF” time. Flyback boost topology where output voltage is higher than input. An accurate duty cycle formula for […]
BQ24295 Smart Battery Charger IC with Boost + OTG
This BQ24295 IC is like a super smart charger chip. This one is not just for charging battery, but also doing many other jobs like boost converter, USB detection, power path control, and even OTG (host power supply). So we can say that this is a full battery charging and power management IC. Let us […]
Do We Need a Freewheeling Diode Across the Inductor in Boost Converter?
So here we are trying to understand whether we must put a freewheeling diode directly across the inductor in a boost converter or not, to safeguard the switching transistor? How Boost Converter Works So in a boost converter, we got one inductor, one power switch like a MOSFET, one diode and one output capacitor. Input […]
DC-DC Boost Module (0.9V~5V) to 5V 600mA USB Step-up Board
So this is a DC-DC boost converter that takes a low voltage (0.9V to 5V) and steps it up to a stable 5V. We use this when we have a small battery, but we need 5V output, like for USB devices. It is super useful for battery-powered projects and small electronics. Main Features How It […]
USB 5V To 24V DC to DC Buck, Boost Power Regulator Module
This is a USB 5V to 24V Adjustable Buck/Boost Converter Module and it helps us step up or step down an input voltage into a higher or lower voltage, which we can adjust as needed. Now let us go through everything in detail step by step. Inputs – Where We Give Power Now we got […]
