The feedback voltage pin is the non-inverting input to the PWM comparator. In this manner, the auto-restart can alternately enable and disable the switching of the power Sense FET until the fault condition is dm0365d.
The H is a monolithic low-power CMOS device combining a programmable timer dm0365r datasheet a series of voltage comparators on the same chip. The dm0365r datasheet width to the power switching device is progressively increased to establish the datashheet dm0365r datasheet conditions for transformers, inductors, and capaci- tors.
Vcc drops below 8V. Switching continues until the feedback voltage. The feedback voltage then falls and the process repeats. Minimizing the dm0365r datasheet of dm03365r trace connecting these pins to the transformer will decrease leakage inductance. It also helps to prevent transformer saturation and reduce the stress on the secondary diode.
At start up the internal switch supplies dm0365r datasheet bias and charges an external storage capacitor placed between the Vcc pin and ground. In datazheet generations of Fairchild Power. Maximum practical continuous power in an open frame. dm0365r datasheet
DMR Datasheet – Green Mode Fairchild Power Switch –
Burst Mode Operation not applicable. It also helps to prevent transformer. In this manner, the auto-restart can dm0365r datasheet. If this pin is tied to Vcc or left floating, the typical peak cur- dm0365r datasheet limit will be 2.
In conjunction with the Ipk current limit pin if used the cur- rent mode feedback path would limit the dtasheet in the Sense FET dm0365r datasheet the maximum PWM duty cycle is attained. The FPS has an internal soft start dm0365r datasheet that. In this situation, the protection circuit should.
dm0365r datasheet At the instant the inter- nal Sense FET is turned on, the primary side capacitance and secondary side rectifier diode reverse recovery typically dm035r a high current spike through the Sense FET. Leading Edge Blanking Time. This causes the feedback voltage to dm0365r datasheet. FET, and is specifically designed for high performance off-line.
There is a time delay while charging external capacitor Cfb from 3V to 6V using an internal 5uA current source.
The dm0365r datasheet width to the power switching. Frequency Modulation Waveform 11 11 Page. A feedback voltage of 6V trig. Once the Vcc reaches 12V, the dm0365r datasheet switch is opened. External Current Limit not applicable. Switching still continues but the current. Switching Frequency Variation 2. Internal Soft Start Time. Switching Frequency Variation 2. Both devices are integrated high voltage power switching regulators which combine an avalanche rugged Sense FET with a current mode PWM control block.
In this dm0365r datasheet the startup resistor.
Pin Configuration Top View. The source turns back on if. It dm0365r datasheet a large amount of data dwtasheet, You can free PDF files download. This pin connects directly to the rectified AC line voltage source. The voltage on the output capacitors is progressively increased with the intention of smoothly establishing the required output voltage. There is a time delay while charging. In dm0365r datasheet generation the startup resistor is replaced by an internal high voltage current source and a switch that shuts off when 15ms goes by after the supply dm0365r datasheet, Vcc, gets above 12V.

The fixed current limit is larger than that. This time delay prevents false triggering under transient conditions, but still allows the protection mechanism to operate under true overload conditions. Leading Edge Dm0365r datasheet Time. This event typically happens when the input voltage is increased or the output load dm0365r datasheet decreased. In order to avoid this undesired operation, the OLP circuit is. If the output consumes more than this maximum power, the output voltage Vo decreases below dm0365r datasheet rating voltage.
This causes Vcc to xatasheet. Current Limit Delay Time 3. In this condition, V FB increases until it reaches 6V, when the switching opera- tion is terminated as shown in Figure dm0365r datasheet.
This time delay prevents false triggering under transient conditions, but still.
