We have developed an AC/DC reference board capable of 12V output, specialized for industrial equipment such as industrial inverters, power conditioners, and PLCs. It is a reference board for low power consumption and compact AC/DC isolated power supply with built-in rectifier circuit so that AC power can be directly input.
It supports single-phase (100V, 200V) and three-phase (200V, 480V) as AC power input, and can be applied to various systems according to customer's application. A DC input terminal is also available as an option.
This reference board uses an isolated power flyback controller IC from Analog Devices, Inc. (model: LT8316EFE#TRPBF). Others are designed using SiC FET (Qorvo model: UJ3C120150K3S) and inductor (Wurth Elektronik model: 7447480102).
Features of the LT8316
- Wide Input Voltage Range: 16V to 600V
- No optical isolator required for regulation
- Quasi-resonant boundary mode operation
- Constant current and constant voltage regulation
- Low ripple light load Burst Mode🄬 operation
- Low Quiescent Current: 75μA
- Programmable current limit and soft start
- TSSOP package with space for high voltage pins
