Low Vp improves efficiency 2. Mounting holes should be no larger than those on the semiconductor package; and should be free of burrs or chamfers.

Constant Current – Zener Reference The Bandgap Reference Although very stable, the circuit of Figure 1 -4 does have a disadvantage in that it requires a supply voltage of 9 volts or more. The resulting output voltage-current characteristic is shown in Figure B. For the single transistor versions, V turn-on and 1. Since AVbe is usually acceptable, V2 should be 1. The hysteresis voltage V H at the comparator input can be calculated using the equation: In this darasheet, the MC, MC sets and regulates the negative output voltage, while the MC, MC acts as a balancing amplifier to regulate the positive output voltage.

If power dissipating element is not located at heatsink ‘s center of symmetry, multiply 17 by 0. The Discrete Sense Circuit — A technique which can provide adequate gate drive and an adjustable, low temperature coefficient trip point is shown in Figure High CMRR amplifier 2.

The circuit shown in Figure senses the voltage on the power supply filter capacitors to predict the imminent power supply failure. Here, the dc feedback signal is compared to 2m6489 fixed frequency sawtooth or triangular wave- form. Because the transformers operate in this mode, they tend to be almost half the size of the equivalent single transistor converters and thereby provide a cost advantage over their counterparts at power levels of watts to 1.

Switchers 2n648 exhibit long hold-up time due to their inherent ability to regulate over wide variations in input voltage. R2 is then given by: This process is iterated until the smallest heatsink is obtained that has the required Osa.

This output, together with the indication output transistor, is activated either by a voltage greater than 2. From Figurewe can determine a range of minimum capacitor values to obtain sufficient ripple attenuation. If jumper ‘B’ is con- nected, S. Control Section The TL provides the pulse- width modulation datasheeg for the power supply.

Therefore select Q1 and Q2 such that: Because the primary winding is driven in both directions, a full wave output filter, rather than half, is now used, and the core is actually utilized more effectively. However, the construction of an infinite heatsink is hardly practical.

No evidence of core saturation 2. An undervoltage-inhibiting circuit is added externally to the control IC.

Output polarity reversal 2. Figure shows a typical diffe- rential error amplifier in a voltage regulator configuration. Consisting of two transistors and a zener diode, it inhibits output pulses ddatasheet the drive voltage is less than 10 V. Load has “latched-up” in some manner usually seen with op amps, current sources, etc. Half-load regulation is equally impressive. Current limit too low 4.

In this section, configurations, specifications and current limit techniques for external series pass elements will be considered. Before these devices can be 2j6489 in the circuit, both protective and drive circuits will have to be designed.

The rectifier ratings are now specified: The transformer, having only a A subtle variation in the method of operation can be applied to either of these circuits.
