MORNSUN has introduced two new drivers SCM1201BTA and SCM1212BTA that feature integrated MOSFETs for the primary side of a push-pull power and can be used in the 1-2W applications with 3.3V and 5V inputs. These new series with wide input voltage range of 2.7-5.5V will not be damaged even under the high input voltage up […]

The role of power supply is crucial for electronic circuits because without sufficient power, the circuit cannot function at its optimal level. On the other hand, an exceeded power supply can deteriorate the circuit components by heating effect. There are usually two choices for power supply topologies; Linear Power Supply and Switched Mode Power Supply […]

Class AB Amplifiers

Introduction Class A amplifiers offer a very good linearity of the output, meaning that the signal is faithfully reproduced, however their efficiency is very low, around 20-30 % in most of the cases. On the other hand, class B amplifiers present a very high efficiency up to 78.5 % but cannot reproduce the output faithfully. […]

Amplifier Classes

Introduction Amplifiers are commonly classified depending on the structure of the output stage. Indeed, the power amplification really happens during that stage and therefore the quality and efficiency of the output signal is dictated by the architecture of the amplifier’s output. The classification consists of an alphabetical arrangement A, B, AB and C that relates […]
