Figure 1. Substituting the diode-capacitor network shown for an inductor allows this switching-regulator IC to deliver 2mA at comparable line and load regulation, with somewhat reduced efficiency. Figure 2. Introducing a MOS driver (IC2) enables the Figure 1 circuit to deliver as much as 20mA. In conventional applications, switching-regulator ICs regulate VOUT by controlling the [...]

Audio Power Meter indicates the amount of power that goes to a loudspeaker. This simple audio power meter circuit uses dual-colour LED that shows green at an applied power level of about 1 watt. At 1.5 watts it glows orange and above 3 watts it is bright red. The audio power meter circuit is connected [...]
