- .. pumps and associated filters: C4 + C5 for the positive rail, C7 + C8 for the negative. Peak-to-peak output ripple is ~10 mV. Output regulation is provided by the charge pump control from the temperature compensated discrete transistor ...26-04-2024
- .. across it to fairly precise and constant values. For example, with R 3 = 430 Ω, the current in LED 2 is approximately 10 mA with 5 V at Q 2 ’s base (TX high). If you use a device such as the HLMP-1000 for LED 2 , its forward voltage ...23-04-2024
- .. this controller skips a certain number of power cycles in between, to vary power to the heaters. In this typical design, 10 full cycles are taken as base. Timer U3 (555) through R2, R4, and C1 decides this by giving output pulses with an ...15-04-2024
- .. state is zero. Below are the timing equations for the test circuit in Figure 5 built with IC1 = TLC393 , R4 = R6 = 10 kΩ, R5 = R7 = 22 kΩ, and +V S = 15 V. Note that V CS falls out of the equations, so the ’on’ time is ...05-04-2024
- .. with R3. Some ’large’ (high current) MOSFETs have gate capacitances of tens of nanofarads, so with R1 = R3 = 10 kΩ it can take several milliseconds for the gate to discharge completely. Now, with C2 = 100 nF and R7 = 10 kΩ, Q3 ...28-03-2024
- .. peak value to the signal end of R1, and adjust R8 for zero indication on the meter. Now apply the maximum level I chose +10 dBu and set R11 for full-scale deflection. R8 must be set first, then R11. Temperature stability is good. According ...21-03-2024
- .. a first-order temperature coefficient of 3.9 parts/1000/ C. As a result, the regulated current decreases about 4% for each 10 C increase in operating temperature. Materials on the topic Datasheet Maxim MAX1685 Datasheet Maxim MAX4162 Datasheet ...20-03-2024
- .. if the final design could attain a 500 ps rise time, this would be too large to ignore as it could give an error in the 10% range. But if we assumed a value for R P (or better yet pre-measured it) we could remove it after the fact. As ...18-03-2024
- .. improving efficiency-promoting synchronicity of charge transfer. Some performance spec’s (V+ = 5 V) are: Impedance of 10 V output: 8.5 Ω Maximum continuous load: 50 mA Efficiency at 50 mA load: 92% Efficiency at 25 mA load: 95% Unloaded ...14-03-2024
