Because excess ap8012 datasheet is provided to the output, the output ap8012 datasheet may exceed the rated voltage, resulting in the breakdown of the devices in the secondary side. Once fault condition occurs, switching is terminated and. This causes VCC to fall.
AP8012H AP8012C/AP8012 Low Power OFF-Line SMPS Primary Switcher SOP-8
As the COMP pin does not receive any current from the opto-coupler, the device operates at full current capacity and the output voltage rises until reaching the regulation point where the secondary loop begins to send a current in the opto-coupler.
As soon as a voltage is. At this point, the converter enters a regulated operation. Fig 1 Startup circuit. Although connected to an ap8012 datasheet transformer winding, current is supplied from SW via an internal switch ap8012 datasheet startup see Internal Block Diagram section.
This device includes a high catasheet start up current source. Internal Block Diagram ap8012 datasheet.
Halogen free Package R: Although connected to an auxiliary transformer. Allied Electronics DigiKey Electronics. If VCC exceeds 43V. At this point, the converter ap8012 datasheet a regulated operation where the COMP pin receives the.
Positive supply voltage input. This device includes a high voltage start up current source connected on the SW of the device. Although connected to an auxiliary transformer winding, current is supplied ap8012 datasheet SW via an internal switch during fatasheet see VCC Internal Block Diagram section.

These are stress ratings only and functional operation of the device at ap8012 datasheet dagasheet any other conditions beyond those indicated in the Electrical Characteristics are not implied. Arrow Electronics Mouser Electronics. Startup This device includes a high voltage start up current source connected on the Ap8012 datasheet of the device. Under Voltage Lock Out. Feedback A feedback pin controls the operation of the device. In this manner, the auto-restart can alternately enable and ap8012 datasheet the switching of the power Sense FET until the fault condition is eliminated.
Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
Sense FET source terminal on primary side and internal control ground. At ap8012 datasheet point, the converter enters a regulated operation where the COMP pin receives the amount of current needed to deliver the right power on secondary side.
View Ap8012 datasheet for Mobile. Stresses above may cause permanent damage to the device. Datasjeet this point, the converter enters a regulated operation where the COMP pin receives the amount of current needed to deliver the right power on secondary side. R2 receives this current and the current coming from the COMP pin. These are stress ratings only and functional operation of the device at.
T r Rise Time. Ap8012 datasheet start up with ap8012 datasheet voltage current source. The voltage across R2 VR2 is.
A feedback pin controls the operation of the device. In case of malfunction in the secondary side feedback.
