Shenzhen Mingjiada Electronics Co., Ltd. maintains long-term stock availability of STMicroelectronics' VIPER17LDTR high-performance offline high-voltage converter. This device belongs to the VIPerPlus series, integrating a robust 800V power stage and PWM controller designed to deliver a compact, energy-efficient solution for flyback topology switching power supplies (SMPS).
VIPER17LDTR Product Description
The VIPER17LDTR is a highly integrated offline PWM controller from STMicroelectronics, primarily used in low-power switching power supplies and adapters.
This VIPER17LDTR is housed in an SO-16 package, featuring an integrated high-voltage start-up circuit and an 800V MOSFET. It can be directly connected to rectified high-voltage DC, significantly reducing the number of external components.
The VIPER17LDTR supports quasi-fixed-frequency current-mode control, helping optimize EMI performance.
Operating in quasi-resonant mode under light or no-load conditions, the VIPER17LDTR effectively reduces switching losses and enhances overall efficiency. Advanced frequency jitter capabilities further lower EMI filter costs.
The VIPER17LDTR also features a burst mode with extremely low power consumption, meeting standby mode energy efficiency regulations. Its standby power consumption is below 30mW and less than 50mW at 265VAC, complying with international standards such as Energy Star and CoC Tier 2.
