Description
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.As AC power input, it supports single phase (100V, 200V) and can be applied to various systems according to customer's application. This reference board uses an isolated power flyback controller IC (type: LT8316) from Analog Devices.Others are designed using a common mode inductor (Wurth Elektronik model: 744821240) and a transformer (Wurth Elektronik model: 750317463)
Features
- 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
Typical applications
- industrial inverters, power conditioners, and PLCs
