Most dimmers use pulse width modulation (PWM) to control the amount of power that is delivered to the lamp. Those that come bundled with a switch faceplate control the firing angle of a Triac on the ...

Obviously, long battery life is a significant design goal for portable devices. Much effort is put into maximizing the efficiencies of the DC-DC converters in these products since that clearly extends ...

This article addresses a characteristic found in many battery-powered products. When power to a circuit is first applied, high peak currents are encountered during the time taken to establish stable ...

Available from multiple sources, the UC384X family of current-mode, PWM (pulse-width-modulated) power-supply controllers offers good performance and has spawned a ...
