The other one i built is for 24v output as i plan to build both of these into a single enclosure as a dual output power supply with different voltage outputs for 2 of my audio devices.
Making a single rail linear power supply.
5 to 15vdc 175ma to 750ma per supply.
Featuring a portfolio with a wide variety of op amps including both rail to rail input output as well as just rail to rail output adi provides the widest portfolio of leading edge pr.
It is basically half the σ22 dual rail psu and possesses the same low noise high current excellent line load regulation wide bandwidth and stability characteristics.
The power dissipation in all dc dc converter designs should always be computed as ics cannot usually deliver maximum output power under all conditions.
As with the single rail version this power supply uses the same type of input transformer which supports 120v or 220v mains input depending how its configured but the secondary outputs on this power supply are connected in series instead through the same rectifier bridge and centre tap connected to ground so we can split the current into positive and negative supplies.
