This boost circuit implements current mode control and senses the LED current via resistor R14. The output voltage is boosted to just over 30V to drive 10 LEDs at a regulated current of 0.35A. Often, ...

There’s a joke in the world of radio that all you need for a HF antenna is a piece of wet string, but the truth is that rudimentary antennas rarely perform well. Random pieces of wire may pul… ...

However, a white LED presents a higher forward-voltage drop than do its colorful counterparts and thus poses problems for operation from a single 1.5V cell. The self-oscillating step-up converter in ...

You can buy small modules with capacitive touch detection ICs — most often it’s the TTP223, a single-button capacitive model with configurable output modes. These are designed to pair w… ...

This simple LED driver circuit allows us to drive up to seven LEDs by using a single NiMH (Nickel Metal Hydride) AA cell. The circuit produces voltage pulses at a much higher level than the input ...

An LED Lamp That Pops Up From A Single Circuit Board. You’ve got to see pictures to appreciate the simple ingenuity behind this lamp, which took three years of research to make.

Shown is an example of a simple circuit (TI reference design PMP9759) that bidirectionally drives current through a TEC; the single-chip buck-boost converter requires a minimum number of components.

Simple Current-Loop ... the 1.25-V reference voltage of the LT317AT regulator in response to the 1- to 2-kHz PWM input applied to the E1/E2 LED ... All circuit power comes from a single ...
