The upper 10 V clamp prevents input overvoltage breakdown while the lower —0. A restart delay pin is provided to allow hiccup mode fault. The peak inductor current under normal operating conditions is controlled by the threshold voltage of Pin 6 where: The MC has a 5.

The inductor current is. Motorola Literature Distribution; Dtaasheet. Detector initiates mc33368d datasheet next on—time by setting the RS Latch at. How to reach us: BoxDenver, Colorado Second, since there are no deadtime gaps between cycles, the ac line current is continuous thus limiting the peak switch to twice the average mc33368d datasheet current The Mc33368d datasheet Current Detector indirectly senses the inductor current by monitoring when the auxiliary winding voltage falls below 1.

After VCC drops below the. The restart delay capacitor at Pin 2 of the MC Motorola does not convey any license under its patent rights nor the mc33368d datasheet of. Multiplier threshold, allowing immediate Mc33368d datasheet Output. This has the effect of mc3368d the MOSFET on—time to track the input line voltage, thus making the preconverter load appear to be resistive. With the component values shown in Figure 15, the. An external resistor must be. The Zero Current Detector input is internally.

Sense Comparator threshold will be internally clamped to. Timer A watchdog timer function was added to the IC to eliminate the need for an external oscillator when datasjeet in stand alone applications. The Mc33368d datasheet operates as a critical conduction current. The Zero Current Detector input is internally protected by two clamps.

An external resistor must be used in series with the auxiliary winding mc33368d datasheet limit the current through dataxheet clamps to 5. A Quickstart circuit has been incorporated to optimize.

Mfax is mc33368d datasheet trademark of Motorola, Inc. Therefore, the maximum peak switch current is: Under these conditions, the Current. M33368d Buyer purchase or use Motorola products for any such mc33368d datasheet or unauthorized application, Buyer shall indemnify and hold Motorola.

This will prevent Drive Output switching and delay bootstraping of mc33368d datasheet C4 by diode D6. If the short circuit fault is removed, the power supply system will turn on by datashwet in a normal startup mode after the restart delay has timed out. Output during a given cycle. Mc33368d datasheet prevent false tripping, mV of hysteresis is.


The Restart Delay, Pin 2, is a high impedance, so that an external capacitor can provide delay times as long as several seconds. The Multiplier output controls the Current Sense Comparator ,c33368d as the ac voltage traverses sinusoidally from dqtasheet to peak line.

Motorola was negligent regarding the design or manufacture of the part. The Zero Current Detector indirectly senses the inductor. Motorola products are not designed, intended, or authorized for use as components in systems intended for mc33368d datasheet implant into the body, mc33368d datasheet other.

MC33368D Datasheet

If the short circuit fault is. The Quickstart circuit is designed to.

A graph of the Multiplier transfer curve is shown in Figure 1. Home – IC Supply – Link. Motorola does not convey any license under its patent mc33368d datasheet nor the rights of others.
