- Many suitable circuits exist for driving LEDs in constant-current mode and from low-voltage sources. For example, references 1 , and 2 show circuits that use switched-mode-regulator ICs and low-voltage sources to supply LED current. To produce a ...18-05-2017
- Energy-harvesting, or “scavenging,” systems extract energy from the ambient environment. Unfortunately, these power generators supply much less energy than do standard batteries. However, thanks to the decreasing size and low-power ...16-05-2017
- Larry Suppan, Maxim Integrated Application Note 657 Placing a load-disconnect circuit on the output of a bootstrapped step-up regulator allows the regulator to start with load currents much higher than would otherwise be possible (Figure 1). During ...09-05-2017
- Maxim Integrated Application Note 1872 This application note presents a circuit that uses a low-power CMOS comparator to provide an LED visual indication of a low-battery condition. This LBO (low-battery-indicator) is achieved by pulsing the LED at ...29-03-2017
- The Design Idea in Figure 1 is a precision current mirror used to drive two strings of five white LEDs. Figure 1. Current source/mirror driving two LED strings. The op-amp has double negative feedback (since M2 inverts the signal at the ...23-03-2017
- Erik Matlin Electronic Design With portable battery-operated devices continuing to add functionality while shrinking in size, printed-circuit-board real estate becomes increasingly valuable. Single-supply circuitry can help by saving space and ...23-03-2017
- All dedicated current-sense amplifiers provide high-side sensing on a positive supply, but you can adapt such circuits for monitoring a negative supply (Figure 1). The positive-supply pin, V+, connects to the system's positive supply, and the ...08-03-2017
- Mark Cherry EDN A single temperature sensor can provide an interrupt to a microcontroller when the measured temperature goes out of range. You need multiple temperature sensors when you have to monitor more than one hot spot. A microcontroller ...06-03-2017
- Introduction High-capacity, multilayer ceramic capacitors (MLCC) have a property often not well understood by electronic designers: the capacitance of these devices varies with applied DC voltage. This phenomenon is present in all high-dielectric ...20-02-2017
- Royce Higashi and Tony Doy, Maxim Integrated Products EDN Low-profile piezoelectric speakers can provide quality sound for portable electronic devices, but they require voltage swings greater than 8 V p-p across the speaker element. Yet, most ...09-02-2017
