The switch current is monitored during the on-phase and the voltage across the SENSE pin is not allowed to exceed the current limit threshold of 108mV (typical). If the SENSE pin exceeds the current limit threshold, the SR latch is reset regardless of the output state of the PWM ...
At the start of each oscillator cycle, the SR latch is set, which turns on the power switch, Q1 (Q2). A voltage proportional to the switch current is added to a stabilizing ramp and the resulting sum is fed into the positive terminal of the PWM compara- tor A2 (A4). When this ...

After the execution of all the basic logic building blocks, a non-volatile 1-bit half adder circuit is proposed. Finally, non-volatile sequential logic circuits (such as SR, JK, D and T latches) have been presented for photonic integrated circuits. Moreover, to the best of our knowledge,...
After the 1ms, the circuit latches into sink-mode. The fault is cleared with a reset of Vin or by resetting the ON/OFF pin. Remote On/Off Control Please refer to the Connection Diagram on page 1 for On/Off connections. Positive logic models are enabled when the On/Off pin is left ...
The operating conditions of the proposed LDO regulator with the SR-Latch switch structure were set to an input voltage of 3.3V to 4.5V, maximum load current of 250 mA, and an output voltage of 3V. As a result of the measurement, it was confirmed that the proposed LDO regulator maintained...
Figure 3 DFF and LUT (SR-Latch) Configurations Design Considerations The output pulse width can be calculated using the equation (counter data × tCNT), where tCNT is equal to the period of the counter CLK input or (1 ÷ counter clock frequency). In the above design, the counter clock ...
the IC will latch off and the system VCCsupply voltage can decrease due to the loss of the aux winding supply. The system VCCwill fall below the lower UV- threshold of the system controller and the system high-voltage start-up circuit will turn-on and VCCwill increase again (Fig. 10)....

The start of each oscillator cycle sets an SR latch and turns on the internal NPN power switch. An amplifier and comparator monitor the current flowing between the VIN and SW1 pins, turning the switch off when this current reaches a level determined by the voltage at VC1 node. An error ...
