The delay time for shutdown is the time required to charge CB from 2. An opto-coupler such as the H11AA and shunt regulator such as the Datashete are typically used to implement the feedback network.
Rockchip RK datasheet V0. Typical continuous power in a non-ventilated enclosed adapter measured at 50C ambient. SN datasheet – doctor- SN datasheet Author: However, even when dafasheet SMPS is in the normal operation, the over load protection circuit can be activated during the load transition.
Overload is defined as the load current exceeding a pre-set level due to an unexpected event.
In this generation the startup resistor is replaced by an internal high voltage current source. At startup, an internal high voltage current source supplies the internal bias and charges the external capacitor Cvcc that is connected to the Vcc pin as illustrated in Figure 4.
The feedback voltage then falls and the process repeats.

Free standing with no heat-sink under natural convection. For stable operation, a capacitor should be placed between this pin and GND.
TempFeedback Source Current vs. Once Vcc reaches 12V, the internal current source is disabled. These parameters, although guaranteed, are tested in EDS wafer test process. This pin is the control ground and the Sense FET source. Because more energy than required is provided to the output, the output voltage may exceed the rated voltage before the over load protection is activated, resulting in the breakdown of the devices in the secondary side.
This reduces the current through the opto-coupler LED, which also reduces the opto-coupler transistor current, thus increasing the feedback voltage Vfb. This parameter is the current flowing into the control IC.
It also helps to prevent transformer saturation and reduce the stress on the secondary diode during startup.
Excessive voltage across the Rsense resistor would lead to incorrect feedback operation in the current mode PWM control.
It is designed to drive the transformer directly. This pin is the positive supply voltage input. This causes the feedback voltage to rise.
When Vcc reaches 12V, the internal high voltage current source is disabled and the power is supplied from the auxiliary transformer winding. This device is an integrated high voltage power switching regulator which combine an avalanche rugged Sense FET with a current mode PWM control block.
Qlt datasheet pdf – datasheet pdf QLT datasheet, Maximum practical continuous power in an open frame design at 50C ambient. In order to d,o565r this undesired operation, the over load protection circuit is designed to be activated after a specified time to determine whether it is a transient situation or an overload situation.
Datasheet Release Date Dztasheet datasheet pdf QL5 datasheet, The voltage on the output capacitors is progressively increased with the intention of smoothly establishing the required output voltage.
As the load decreases, the feedback voltage decreases. Because these protection circuits are fully integrated into the IC without external components, the reliability can be improved without increasing cost.
When the temperature exceeds approximately C, the thermal shutdown is activated. At startup, the internal high voltage current source supplies internal bias and charges the external capacitor that is connected to the Vcc pin.
Because of the pulse-by-pulse current limit capability, the maximum peak current through the Sense FET is limited, and therefore the maximum input power is restricted with a given input voltage. TempBurst Mode Enable Voltage vs.
