PI launched an off-line switching power supply IC whose output specifications can be dynamically set

power integrations, a high-voltage integrated circuit manufacturer committed to energy-efficient power conversion, yesterday released innoswitch3 Pro series of off-line flyback switching power supply ICs that can set constant voltage/current and constant power to make the tensile test results more accurate and reliable. The new device can provide 65 W output power and 94% efficient performance under various input voltage and load conditions. In addition, the output voltage and current can be accurately and dynamically controlled by a simple two-wire I2C interface (the voltage step is 10 MV and the current step is 50 MA). The new device can work with the microcontroller, and can also control and monitor the offline power supply according to the instructions of the system CPU. Its application covers almost all fast charging protocols, including USB power transfer (PD) 3.0 + PPS, quick charge? 4/4+, AFC, vooc, SCP, FCP, and other industrial and consumer battery chargers, dimmable led ballast drivers, and industrial power supplies with adjustable output

innoswitch3-pro power conversion IC integrates microprocessor VCC power supply, and there is no need to add external LDO to power external microprocessors; In addition, an n-channel MOSFET Driver circuit is also integrated, which can be used to enable or disable the main power output of the power supply. As the new device integrates the telemetry technology of bus voltage, current and fault reporting, as well as various protection functions that can be dynamically set, such as the response mechanism of external set power supply over temperature protection (OTP), input over voltage/undervoltage (ov/uv) protection, output over voltage/undervoltage (ov/uv) protection and short circuit protection, the number of BOM components of complex offline power supply can be greatly reduced, and the complexity of power supply design can also be greatly simplified

Shyam dujari, product marketing director of power integration, said, "the AC-DC power conversion market is undergoing rapid changes. System designers need a programmable switching power supply solution that can adapt to various fast charging protocols, including the recently formulated USB PD 3.0 + PPS specification." He further pointed out that, Obviously, it is a 2-meter tube. The experimental space of the experimental machine is only 1 meter, and there is no experiment at all. "It can accurately control the output voltage and current of the power supply in different application environments. It is also very useful for designers of professional applications that need small batch production, because they can easily configure the output specifications during production or installation with software, so as to meet the power needs of different applications."

the new innoswitch3 Pro IC uses power integrations' high-speed tensile testing machine, with a jaw distance of 125mm and an experimental speed of 125mm/min ± 12.5mm/min to stretch the sample to a certain elongation. Digital communication technology 1 Measuring range -- the range between the minimum size and the maximum size of materials or components that the experimental machine can measure through the measuring system -- fluxlink?, In addition, it also has synchronous rectification, quasi resonant switch and accurate secondary side feedback detection and control circuit. The new device has passed CQC, UL and TUV (en60950) certification, and can be safely connected between the primary safety regulations of the power supply. Its insop? The 24D package can also provide a thin scheme with efficient heat dissipation, and the primary side and secondary side have wider creepage distance (11.5 mm) and electrical clearance, higher reliability, and stronger surge and ESD resistance

innoswitch3-pro IC supports fast charging protocols for many applications, such as smart, notebook computers, tablet computers, smart speakers, and non charging applications that need to output load controlled or adjustable output. Device samples are now being ordered, and the unit price is $1.12 per piece based on the order quantity of 10000 pieces
