The feedback current can change from 0mA full output power to about 0.

Ap datasheet offers a large amount of data sheet, You can free PDF files download. The output current is the parameter in this case.

Phase N, average detector Figure The zener diode D6 was not connected during the measurements Figure 6: The voltage across R2 VR2 is. Picture of the Converter 2. The diode D7 between capacitor C7 and C4 ensures the proper start-up of the converter.

A feedback pin controls the operation of the device. This circuit inhibits ap PWM comparator. Because excess energy is provided to the output, the output voltage may exceed ap datasheet rated voltage, resulting in the breakdown of the devices in the secondary side. Depicted output regulation and overall converter efficiency characteristics measured at different working conditions show good performance of this simple VIPer12AS application in such difficult working environment.

Auxiliary under voltage lockout with hysteresis. The output current flowing to the output capacitor C3 is discontinuous for the buck-boost converter unlike the above described buck converter. Exposure to absolute maximum. This device includes a high voltage start up current source connected on the SW of the device.

T j Junction Operating Temperature. The input capacitor C1 is charged from line via one way rectifier consisting of diodes D1 and D2. T j Junction Operating Ap datasheet. In this app8012 phase the source terminal of the VIPer12 sees negative level of forward biased D5 and negative output voltage when referenced to ground.

For this reason the reference ground is common for an input and output connection terminal.

Although connected to an auxiliary transformer. The converter is called inverting.

No license is granted by implication or otherwise under any patent or patent rights of STMicroelectronics. Diode D6 limits the output voltage at light load condition and it also protects the U2 voltage regulator. Assembly Solder Side not in scale Figure 4: The outline dimensions are 38x29mm. One has to take into account the slight variation of the output voltage with the load.

Fig 1 Startup circuit 2. This allows the inductor current to flow also through D4 and supply the VIPer12 and give the feedback information about output voltage. This publication supersedes and replaces all information previously supplied.

The SW pin is designed to connect directly to the primary lead of the SW transformer and is capable of switching a maximum of V. Figure 8 depicts the dependency of the efficiency on the input voltage parameter is output current while Figure 9 shows the dependency on ap012 output current parameter is input voltage. The H is a monolithic low-power CMOS device combining a programmable timer and aap series of voltage ap datasheet on the same chip.

Two diodes in series are used for Fatasheet reasons to sustain burst pulses of 2kV. T c Case Operating Temperature. It means the IC and corresponding supply and feedback loop circuitry is floating. The circuit is EMI compliant both emission and immunitywhen a small input filter is added. Regulator U2 accommodated in DPAK or SO-8 package is optional and can be assembled if the power supply for a microcontroller or logic part is required. The physical appearance of the dtaasheet can be observed from Figure 5.

Over temperature, over current and over voltage. The voltage feedback loop is provided via zener diode D3, resistor R3 and capacitor C6. To counter this effect, the device employs a leading edge blanking LEB circuit.

The updated every day, always provide the best quality and ap datasheet. The SW pin is designed to connect directly to the primary lead of the transformer.

Dataheet above may cause permanent damage to the device. The channel 4 red shows the inductor current. It is dedicated for building an auxiliary power supply based on the VIPer12AS monolithic device with rather low output power required.
