  • Design to meet automotive and medical application requirements

It meets the isolation protection requirements of 2 MOPP and features an isolation voltage of 5000VAC, system operating voltage up to 849VDC, isolation capacitance as low as 3.5pF, and complies with IEC/EN 60601 standard. 

Its working temperature range is as wide as -55℃ to +125℃, making it work stably in different harsh environments. It runs well with 55% load at 125℃, enabling it for applications of high temperatures, such as automotive electronics.

  •  4 in 1, 4 adjustable outputs of 3.3V, 3.7V, 5.0V, 5.4V achieved by TRIM

The chip adopts a unique control architecture with a built-in feedback loop, which can quickly respond to load changes and achieve regulated output. 4 different output voltages of 3.3V, 5V, 3.7V, and 5.4V can be precisely adjusted and realized by the pin TRIM. Using the same module to get different outputs for different devices can help to decrease the BOM list and reduce the management cost.

  • Ultra-compact to save space

This highly integrated product in SOIC16 package is only 0.35g (Typ.). It is suitable for the space-limited design of handheld devices and portable devices to save customers PCB layout space, and perfectly match customers’ usage scenarios and industrial technology trends.
