Application Note

Reference design for double output SMPS for power line

modem applications using ALTAIR04-900 primary controller

Introduction

This application note introduces a new “all-primary sensing” switching regulator ALTAIR04-

900, used to build an innovative solution to supply a power line communication.

A demonstration board, implementing a wide-range double-output power supply, has been

developed and the results of its bench evaluation are reported in this document.

The board uses the new ALTAIR04-900, a quasi-resonant (QR) current-mode controller IC

specifically designed for QR ZVS (zero voltage switching at switch turn-on) flyback

converters, which combines a high-performance low-voltage PWM controller chip and a

typical 16 RDSon, 900 V, avalanche-rugged power MOSFET in the same package.

The device is capable of providing constant output voltage regulation using primary-sensing

constant voltage loop (CV loop). This eliminates the need for the optocoupler and the

secondary voltage reference while still maintaining quite accurate regulation.

Also, using the primary constant current loop (CC loop), it is possible to set the maximum

deliverable output current without any secondary components or current sensor.
