.. input (4.5 V to 32 V) power source. It can switch between high efficiency Burst Mode® operation and low noise constant frequency mode, making it attractive for both portable and noise-sensitive applications. The LTC3260 is available ...
.. using PSpice transient analysis of the circuit, with the ac input source set for V AMPL = 2 V, V OFF = 2.3 V and frequency of 1 kHz. In this case, V I_MIN = 0.3 V and the transient analysis shows a clipping at the bottom of ...
.. drawing only 70 uA quiescent current in user-programmable Burst Mode® operation. Its peak current mode, constant frequency PWM architecture provides positive control of inductor current, easy loop compensation and superior ...
.. gated with the clock using the AND1 gate, generating an RZ waveform (Figure 2b). The RZ signal clocks a D-FF connected as a frequency divider. The RZ signal is then gated with the Q and /Q outputs of the flip-flop, separating alternating ...
.. by a suitable choice for the gain of the amplifier DA1-1. It can be calculated by This is correct within the operational frequency range only. This device has excellent response speed. It is less than one half-wave of the signal. ...
.. radiated emissions, which are proportional to this area, to the value of the current, and to the square of the current frequency, and they may disturb the circuit itself and the measuring equipment.
.. the circuit will reject noise contained in the input signal and will produce a rectangular output signal at the same frequency as the input. Whether you implement a Schmitt trigger using transistors, op amps, or comparators, you ...
.. phase shift into the regulator control loop feedback, compromising stability. Many engineers have seen the tell-tale low frequency sine wave riding on the regulator output. Performing transient testing on an assembled system allows a ...
.. voltage ranging from 3.6 V to 20 V (circuit shown in Figure 1). The LTC3626 employs a unique controlled on-time/constant-frequency, current-mode architecture, making it ideal for low duty cycle applications and high frequency ...
.. ideal candidates for laboratory pulse-generation service. A simple implementation uses Linear Technology's LTC3803 constant-frequency flyback controller, IC 1 (Figure 1). The controller self-clocks at 200 kHz, and applying a sample of ...
