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 […]
Voltage Control and Protection
AMS1117 1A LDO Voltage Regulator IC – 3.3V, 1.8V, 2.5V, 5V Regulators
In this post I will be talking about one famous voltage regulator IC called AMS1117. It is a 1 Amp Low Dropout (LDO) Linear Voltage Regulator and we can get it in both fixed output types and also adjustable output version. It is super small, easy to use and available in SOT-223 package mostly, which […]
Designing a Power Factor Correction (PFC) Circuit Using UC3854 – Key Considerations
The IC UC3854, what it does is, it helps in active power factor correction, right? Now normally, if we don’t correct the power factor, then power system will pull current from the AC mains in a way that’s not a nice sine wave but rather distorted. This IC takes care of all the control stuff […]
USB 5V To 24V DC to DC Boost Power Regulator Module
This is a USB 5V to 24V Adjustable Boost Converter Module and it helps us step up a lower voltage into a higher 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 three ways to power this […]
TPS24710/11/12/13 Hot-Swap Controller Circuit Explained
When we talk about hot-swap controllers, it is basically an electronic device or integrated circuit (IC) that allows you to the insert or/and remove circuit boards, modules or parts within an active system without having you to switch off the system. It regulates the surge current whenever a component is installed and protects from short […]
Simple Boost Converter Circuit Diagrams using Transistors
In this post I have explained a few very simple boost converter circuits using only BJTs, or transistors. Let’s learn more. What is a Boost Converter A DC boost converter circuit is designed for stepping-up or boosting a small input voltage levels to a desired higher output voltage level, hence the name “boost” converter. Since […]
