Product Details

300W 12V DC/DC Boost Converter Voltage Step-Up Board with TL494 IC

This 300 watt boost converter steps up your vehicles 12 VDC output (11 to 27 VDC max) up to 48 VDC for use with high power amplifier boards. Select 24, 30, 36, 40, or 48 VDC output via four DIP switches located on the board. Precision voltage adjustments are accomplished through the surface mount potentiometer built onto the board.

A Texas Instruments-designed TL494 pulse-width-modulation control IC provides stable, military-grade voltage output, regardless of voltage setting. Additionally, low-voltage and over-voltage input protection is built-in and a current sensing fan kicks-on when current output is greater than 3 amps. Further protection is provided by two 25A ATC automotive fuses.

This boost converter is different than many car audio electronics and amplifiers. With 12 VDC input power, the boost converter is in an on condition, and is boosting voltage to the preset output.

To turn boost converting off, 12 VDC needs to be applied to the EN input terminal. It is recommended that you wire EN to a SPST switch and then to 12 VDC in the event you need to turn boost converting off. The current consumed by this boost converter is 20 mA when not driving a load.

Note: The manual incorrectly states that the LEDs will illuminate green. The LEDs actually illuminate blue when the boost converter is operating correctly.

Features and Specifications:
• Input voltage: 11 to 27 VDC
• Output voltage: 24, 30, 36, 40, 48 VDC
• Quiescent current: 20 mA
• Low input voltage protection
• High input voltage protection
• Dimensions: 4.80" L x 3.60" W x 1.5" H

300W 12V DC/DC Boost Converter Voltage Step-Up Board with TL494 IC

Would this step up 12v battery into 30v at 12 AMPS

Asked by: shayd
The transformer has a 300 watt output rating regardless of the voltage output. Simply divide wattage (300) by voltage to receive amperage. 300 watts/30 volts = 10 amps....300 watts/10 volts = 30 amps...

will this power the 2x300W TAS5630 Class-D Amplifier Board Part # 320-309?

Asked by: jammer64
Unfortunately this will not provide enough output for that board. I would only recommend this for the 2x100 watt or smaller boards.
