  1. Capacitor type charge pumps are a well-known, simple, efficient, cost-effective (and therefore popular!) method for inverting and multiplying voltage supply rails. Perhaps less well known, however, is that they also work just as well for dividing ...

  2. The Power Integrations TOPSwitch family of integrated flyback-regulator ICs provides exceptional performance in small, low-pin-count packages. For the lowest-pin-count packages, the multifunction, or M, pin serves multiple purposes, including ...

  1. Circuits Supply Light Maxim MAX1685 MAX4162 MAX5035
    As the latest generation of new LEDs achieves higher levels of power and efficiency, use of these devices extends to new areas, such as flashlights and vehicular applications. High-power LEDs are finding use even in ambient lighting, long the sole ...

  2. When a design needs auxiliary voltage rails and the associated current loads are modest, capacitor pump voltage multipliers are often the simplest, cheapest, and most efficient way to make them. The simplest of these is the diode pump voltage ...

  3. When analog circuits mix with digital, the former are sometimes dissatisfied with the latter’s usual single supply rail. This creates a need for additional, often negative polarity, voltage sources that are commonly provided by capacitive ...

  4. The circuit in Figure 1 shows an electronic switch driven by a momentary pushbutton, which turns the power alternately on and off. It was designed for battery-powered equipment. The easiest way to implement it is to use a flip-flop IC, such as the ...

  5. When a switch-mode power-supply controller, such as NCP1200 , operates at a high ambient temperature, you should protect the entire power supply against lethal thermal runaway. The NCP1200 operates directly from the power mains without an auxiliary ...

  6. A typical SMPS (switch-mode power supply) uses a reference voltage and an optocoupler to regulate the output voltage. The optocoupler carries the isolated information from the secondary side to the primary nonisolated side and ensures proper output ...

  7. Many systems derive 15 V supplies for analog circuitry from an input voltage that may be above or below the 15 V output. The split supply requirement is usually fulfilled by a switcher with a multiple-secondary transformer or by multiple switchers. ...

  8. For a recent design project, a robust power supply was needed to control the gates of high-side FETs. Optocouplers readily translate the logic signals up to the correct control voltages to drive the FETs. However, to ensure that the FETs turn on ...
