The input circuit is a dstasheet wave voltage doubler when connected for Vac operation with both halves of the bridge connected in parallel for added line surge capability. This process is iterated until the smallest heatsink is obtained that has the required Osa. Ripple test data for various types of capacitors is shown in Table The pulse generator is run at a low enough duty cycle to allow the core to reset. Commercial Heatsinks As an aid in selecting a heatsink, a representative listing is shown in Table Also, a trend has begun toward higher switching frequencies to further reduce size and datsheet.

The primary generally goes on first and then the secondary wind- ings. Earlier “lytics” usually lacked this rating and often overheated.

It has two clear advantages over the push-pull datsheet. Under this stipulation, the gap directly controls the LI parameters. However, the same considerations apply for pass elements used with negative regulators.

Output current limit protection is achieved by datsheet a current sense transformer Datasheeh. Although foldback current limiting allows use of smaller pass element transistors for a given regulator output current than does constant current limiting, it does have a few disadvantages. The output current at which this occurs is Ik, the “knee” current.

Therefore, 0cs is found to be 0. Line resistance between sense points and load 5. A partial list of companies is shown in Table Motorola does not assume any liability arising out of the application or use of any product or circuit herein described.

This is accomplished by providing a separate low voltage input supply for the pass element. At Vac, full-load voltages are 5. It consists of a resistor and a zener diode. However, the flyback datahseet which evolved from this configuration deliver only the inductive energy stored in the choke to the load.

However, the checklist provided will help the designer pinpoint the problem in the majority of cases.

Xatasheet, to switch ef- ficiently at higher frequencies, several amperes of drive may be required on a pulsed basis in order to quickly charge and discharge the gate capacitances.

As the load is removed or input voltage increases, a slight rise in output voltage will signal the control circuit to deliver narrower pulses to the inverter, and conversely, as the load is increased or input voltage decreases, wider pulses will be fed to the inverter.

A simple way of lowering the effective value of Zol is to make an impedance transformation with an emitter follower, as shown in Figure Total core gap is mils, and primary- winding inductance is 4. Therefore, an increase in control-signal amplitude causes a corresponding linear decrease of output pulse width. Newer designs in the to kHz region end up at about 6: Very often a mV switching spike at the output may be attenuated considerably at the load itself due to the series inductance of the connecting cables and the additional filter capacitors found in many logic circuits.

Ground Loops and Remote Voltage Sensing Ground Loops Regulator performance can also suffer if ground loops in the circuit wiring are not avoided. For single transistor converters, the snubber shown in Figure is generally used. Values for 0jc and 0sa are found on the device and heatsink data sheets, while 0cs is given in Table This can be found from: Cref is chosen to be 0.

When R2 is bypassed, CR1 is necessary for protec- tion during short-circuit conditions. Dual Overvoltage Protection — The circuit shown in Figure uses the MC to provide overvoltage sensing for a split supply. Other characteristics such as static regulation specs are comparable, while ripple and load transient response are usually worse.

Typical tolerances would be: The TL has an internal 5. Returning to the above curves, the full- wave circuit will be considered. In the event that a fault condition has caused the crowbar to fire, a signal is sent to the control section via jumper ‘A’ or ‘B.

The circuit operates in the following manner:
