An arrangement for enhancing the available energy storage capability of a hold-up energy storage element for use with the step-up or boost regulator stage of a power supply enables use of smaller hold-up storage elements, such as capacitors. The circuit stores energy at the boost regulator outp...

Therefore, the minimization of the hold-up-time active during hold-up time period, i.e., when the ac line is capacitor size is an indispensable design step in izing absent and the front-end power-factor-correction (PFC) the power density of ac-dc computer power supplies. The circuit ...
ix. To stop and maintain position as in “line up and hold” and “hold position.” The former means that an aircraft is cleared to line up for takeoff but must obtain clearance, while the latter means that the aircraft should stop movement on the ground and maintain its existing position...
A sample-and-hold circuit includes a first switch element which is opened or closed in accordance with a first control signal so as to selectively connect an input signal terminal for receiving an input signal to an internal terminal, a non-linear element for connecting the internal terminal to...
Since the delay from ϕ1 to ϕ2 is constant, if domino input does not set up in time, the circuit will fail at any clock frequency. The same problem occurs at the interface of a ϕ1 transparent latch to ϕ2 domino and of a ϕ3 transparent latch to ϕ4 domino. Another ...
Careful OPAMP (circuit) design needs to be done. Especially on * delay to come out of satuartion * ringing time and amplitude .. the signal needs to settle within short time Added: In both cases the output of the second OPAMP may be used for a guard ring around the capacitor node to...

To make your life easier, why not just put the complete supercap hold-up circuit, including its charging resistor and steering diodes, after (and more-or-less separate from) the LM2676 circuit? You would have to adjust the output voltage to account for the steering diode voltage drop, or...
