Note that the greatest demand on the transistors SOA datadheet occurs when the output of the regulator is short circuited and the pass element must support the full input voltage and short circuit current simultaneously. Adjustable minimum overvoltage duration before actuation to reduce nuisance tripping in noisy environments.

Because the designer and component manufacturer must work as a team to bring this about, companies like Motorola that are looking to the future will continue datasueet dialogue with designers to keep abreast with their current and future product needs. Low Zol 26489 2. In order to simplify the design of the input supply see Section 8V IN is chosen to be 16V average with a 3V p-p ripple at full load and up to 25V at no load.

To provide higher currents than are available from monolithic technologiesan IC regulator will often be used as a driver to a boost transistor.

The pulse width modulator comparator provides a means for dataaheet error am- plifiers to adjust the output pulse width from the maximum percent on-time, established by the dead time adtasheet input, down to zero, as the voltage at the feedback pin varies from 0. The operating model for this circuit is actually the buck regulator discussed earlier.

Internally, most of these resemble the functional configuration shown in Figure Linear I ‘ Switcher i Cost 1 1 1! In bridge circuits, clamp diodes can be used to limit these voltage spikes. For illustrative purposes, pass elements for only positive regulator types will be discussed. The procedure for finding the right component and checking its fit is as follows: At each datasneet of the line the output of the comparator discharges the delay capacitor C D.


Instead of storing energy in the transformer and then delivering it to the load, this circuit uses the transformer in datsheet active or forward mode and delivers power to the load while the transistor is on. Here devices that would normally be used in switchers from 10 to watts are listed next to circuits in which they would generally be used. Preliminary designs using the chosen regulators and circuit configurations are then possible. When higher output drive currents are required for single-ended operation, Ql and Q2 may be connected in parallel, and the output mode control pin must be tied to ground to disable the flip-flop.

Use Parts Listed Below.

C n should be a high frequency type capacitor. If not included, regulation would be lost at low output currents. Aside from rather unique drive requirements, a FET is very similar to a bipolar transistor. Although any of these regulators may be used, usually it is most economical to use the 1 ampere MCC in this configuration.

For an electronic circuit load, however, the load resistance must be known in order to determine the output voltage: Depending on which regulator type is used, this config- uration can provide output currents in excess of 3 A.

Standard ferrite cores work fine here and in the high power converters as well. The difference is referred to as operation in the discontinuous or continuous mode, and the waveform diagrams are shown in Figure However, since the sense and ground leads are usually rather long, care must be exercised that their associated lead inductance is minimized, or loop instability may result. As the output current increases, the voltage drop across Rsc increases, propor- tionately.


However, the construction of an infinite heatsink is hardly practical. Therefore, 0cs is found to be 0. Unfortunately, there is no exact step-by- step procedure that can be followed which will lead to the ideal regulator and circuit configuration for a specific application. The shortest possible propagation delay is thus obtained.

Practical solutions to this problem include limiting the minimum load and using the right amount of filter capacitance to give the regulator time to respond to this change.


To see a list of open positions, click here. This is particularly important in many small Figure For optimum regulation, current out of pin 5, I5, should not exceed 0.

If power dissipating element is not located at heatsink ‘s center of symmetry, multiply 17 by 0. The circuit shown in Figure may be used with almost any type of regulator circuitry; however, the circuit shown in Figure should only be used in linear type supplies where the filter capacitor is isolated from the line.

Other switching-regulator schemes place the control IC at the primary side of the transformer, where the transistor emitter current is sensed for overcurrent protection.

This technique ultimately results in the use of foil for the higher current 20 A low voltage windings. Control Circuit Topologies When it is necessary to drive two or more power transistors, drive trans- formers are a practical interface element and are driven by the conventional dual channel IC just discussed Figure 1 A.
