step up or down?

[one1]

I have a tda 7498, it is recommended 32v 7A I have a 48v 8A PS can I use a step up or down module to reach my desired voltage from the 48v supply my other supply is a 24v 6A brick. 36v supply are expensive and I figure I could spend 5 or 10 bucks and use a module.what do you all suggest

Oh my... sorry... If you got a calamity with the interpretation of a Walt Whitman poem I could probably help you...

No Problem,Not really a Calamity,but just curious,I think I might use a step down module since the power is already there I think the noise will be low,here is a example of what I want to use http://www.ebay.com/itm/371112400294
Module parameters:
Module Properties: non-isolated step-down constant current , constant voltage module (CC CV) charging module
Input voltage : 7-40V
Output voltage :1.2-35V continuously adjustable
Output Current: 8A ( when power tube's temperature exceeds 65 degrees, please add cooling fan )
Constant current range :0.2-12A ( adjustable )
Turn lamp current : constant current value * ( 0.1 ) , turn the lamp current and constant value linkage, such as constant current value is 3A, turn the lamp current is set to a constant current is 0.1 times (0.1 * 3A = 0.3A).
Lowest pressure : 1V
Output Power: Maximum power is about 300W
Conversion efficiency : up to about 95%
Operating frequency : 300KHZ
Output ripple : 20M bandwidth
Input 24V Output 12V 5A ripple around 50mV ( excluding noise )
Operating temperature : Industrial grade (-40 ℃ to +85 ℃) ( please note the actual use of the power tube temperature , high temperature heat strengthened please )
No-load current : Typical 20mA (24V switch 12V)
Load regulation : ± 1% ( constant )
Voltage regulation : ± 1%
Dynamic response speed : 5% 200uS
Potentiometer adjustment direction : clockwise ( increase ) , counterclockwise ( decrease ) . the potentiometer(CV) closed to the input voltage is used to regulate voltage, the potentiometer(CC) closed to output voltage is used to regulate current (CC)
Indicator : dual color indicator , charging indicator light is red , the green light means fully charged ( No load is green )
Output short circuit protection : Yes , constant current
Dimensions : 65 * 47 * 23.5 mm

Ops, I edited my post while you were replying.

Sorry about that.

No, actually I don't know Jack Squat about him.

You have me beat there too.
