Figure 1: Thermal resistance comprises multiple stages, from junction to ambient

The principles that apply to current flow, in terms of resistance, can be likened to the resistance that heat encounters when flowing from hot to cold bodies. Every material and its interface will have a thermal resistance, and these figures can be used to calculate the rate at which heat is removed from its so

The SIMO DC-DC Converter - The Audio Amplifier's Best Friend

Click image to enlarge

Figure 1. Small wireless audio devices have challenging size and battery life requirements and are expected to provide excellent audio performance.

Generally, traditional switch mode power supplies (SMPS) are considered to be very noisy compared to that of the low-dropout (LDO) regulators. The switching action associated with switching regulators generates noise and resulting harmonics, which can affect the overall system performance in audio applications. Th
