Although the LSIB-HPULN PS is the "High Current" version of the "High Performance Ultra Low Noise" Power Supply delivering up to 5 ampere for power-hungry devices, the real benefit is the dramatically reduced noise through 10x LT3045 in parallel operation.
This current might not be necessary in your application, nonetheless this fact is worth this power supply to become our recommendation.
 
"Ideal Diode Bridge" rectification
What makes this LSIB-HPULN PS very special, is it's rectifier:
The LT4320 is an "Ideal Diode Bridge" controller that drives four MOSFET's resulting reduced power dissipation and heat. 
Comparing to the Schottky's voltage drop of ~ 0,4V, the MOSFETs with it's resistance of ~ 0,009 Ohm causes a minimal voltage drop only. This makes it possible to use smaller transformers regarding their output voltage and their power rating. See the picture above for a comparison between the "Ideal Diode Bridge" controlled HPULN and the known HPULN with Schottky diodes.
Please notice, that the controller needs 9VDC to work, the used transformer should be >9VAC.
 
Anti-transformer-ringing snubber
The LSIB-HPULN has a snubber option, which makes it possible to significantly reduce transformer ringing. Please see "Quasimodo PCB" for more information. In case of ordering this power supply with a transformer, the snubber will already be configured. In case it's ordered alone, the two film capacitors will be delivered unpublished, to measure your transformer and publish necessary parts (a resistor is necessary, it's resistance is to find out with Quasimodo).
The LSIB-HPULN power supply can also be used without a snubber.
 
Limited offer: The Quasimodo PCB is also part of delivery!
 
With a bigger heatsink mounted it is also capable to better dissipate heat from the regulators.
 
The scope of application is a main power supply for any kind of devices with a need of up to 5 ampere, i.e.:
- Audio interfaces
- DAC's
- Small amplifiers
- Audio-Computers
 
As usual this power supply comes fully assembled and tested for seamless working.
