What is an Integrated Circuit (IC)?
Before the discovery of ICs, the basic method of making circuits was to select the components like diodes, transistors, resistors, inductors and capacitors and connect them by shouldering. But due to size and power consumption issues, it was necessary to develop a small size circuit with less power consumption, reliability and shockproof.
After the invention of the semiconductors and transistors, things were quite simplified to a particular extent, but the development of integrated circuits changed electronics technology’s face. Jack Kilby from Texas Instruments and Bob Noyce from Intel are the official creators of integrated circuits, and they did it independently.
The integrated circuit is a fundamental concept of electronics that builds on other basic concepts previously discussed in our syllabus. Therefore, for a quick reference, go through the articles listed below:

Description for the LMR16030
The LMR16030 is a 60-V, 3-A SIMPLE SWITCHER step-down regulator with an integrated high-side MOSFET. With a wide input range from 4.3 V to 60 V, it is suitable for various applications from industrial to automotive for power conditioning from unregulated sources. The quiescent current of the regulator is 40 µA in sleep mode, which is suitable for battery-powered systems. An ultra-low 1-µA current in shutdown mode can further prolong battery life. A wide adjustable switching frequency range allows either efficiency or external component size to be optimized. Internal loop compensation means that the user is free from the tedious task of loop compensation design. This also minimizes the external components of the device. A precision enable input allows simplification of regulator control and system power sequencing. The device also has built-in protection features such as cycle-by-cycle current limit, thermal sensing and shutdown due to excessive power dissipation, and output overvoltage protection.
The LMR16030 is available in an 8-pin HSOIC package with exposed pad for low thermal resistance.
The new product, LM76003, requires very few external components and has a pinout designed for simple, optimum PCB layout for EMI and thermal performance. See the device comparison table to compare specs.
