This document describes a double output SMPS module for power line applications, using the ALTAIR04-900 primary controller. The module features universal input mains range, double output voltage, optoless constant voltage-constant current output regulation, etc.
The EVLALTAIR900-M1 is a double output SMPS board designed for power line applications. It utilizes the ALTAIR04-900 primary controller, a quasi-resonant current-mode controller IC combining a PWM controller and a Power MOSFET. The board implements a 7.5 W double output wide range mains adapter with constant voltage - constant current regulation, developed to build an innovative AC-DC adapter for power line communication based on the ST7580.
| Input mains range | 90 - 264 Vac, frequency 45 - 65 Hz |
|---|---|
| Output voltage 1 | 13 V @ 0.55 A |
| Output voltage 2 | 3.3 V @ 100 mA |
| Controller IC | ALTAIR04-900 |
| Efficiency | > 70% |
It is designed to build an innovative AC-DC adapter to supply a complete power line communication based on the ST7580.
No, it eliminates the need for the optocoupler and the secondary voltage reference by using primary-sensing constant voltage loop regulation.
