So if the resistor is rated at 10W and the battery is 4.2V, the resistor have to be at least 4.2V²/10W=17.6Ω x4.2/4 - 1 = 0.05 = 5% but is (4 - 4.2)/4.2 = -0.0476 = -4.8%
The boost converter’s output voltage can be fixed or adjustable, using resistors to set the desired output voltage.Current Limit: Boost converters usually specify peak current limit, not load current. Note that the greater the difference between VIN and VOUT, the lower the available load current...
I2C devices are are 3.3V these days. “In general, in a system where one device is at a higher voltage than another, it may be possible to connect the two devices via I2C without any level shifting circuitry in between them. The trick is to connect the pull-up resistors to the lower...
RDS(ON) of the internal switches determines sink and source current, but external series resistors are used to reduce drive current and, thus, affect edge rates. As seen in Figure 4, high-side on-resistance and the external series resistor REXT form the gate resistor in the charging path,...
SPICE (Simulation Program with Integrated Circuit Emphasis) was initially developed to mathematically predict integrated circuit behavior. It is also used to predict the effects of passive components, such as resistors (R), inductors (L), and capacitors (C), within circuits. Passive R, L, and ...
The device uses the following formula to calculate the power: pinn = 2 ∙ Kp + Ki 1 1 − z− 1 err (2) where err is equal to the voltage error (target output voltage - real output voltage) divided by VerrLSB = 0.473 V (in case standard bulk partitioning resi...
The MegaSurge Series of inrush current limiting NTC thermistors offer a simple and cost-effective alternative to using wirewound resistors in combination with timers and relays. These thermistors not only reduce costs but also simplify designs significantly. Moreover, they enhance safety by eliminating...
4. FEEDBACK RESISTORS: Use data sheet Equation 2 to size the feedback resistors for the required output voltage. Although the data sheet recommends 10 kΩ as an optimum value for R2, larger or smaller values can be used at the risk of noise being injected into FB or higher current ...
I don't know what the transfer function of CdS etc., photoresistors are in terms of resistance vs. optical input power. If you can find that out and work out how much light or optical power each resistor is receiving then you can use a behavioural resistor to set the resistance as a ...
