High Quality Breadboard Power Supply

This high quality breadboard power supply delivers heat away from the power supply better than the "regular" breadboard power supplies. Like the "regular" power supplies, it fits directly onto the most breadboards (MB-102) so that no wiring is needed for powering up the breadboard power rails.

Features:

• Independent dual-channel output (3.3V and 5V output at the same time)
• On-board barrel connector for connecting to an AC/DC adaptor
• Optimized thermal design with PCB copper and vias as heat sink
• Additional aluminium heat sinks + heat-conducting stickers included for extra cooling
• Inverse input polarity protection
• Short circuit protection
• Thermal shut down protection
• Plug and Play design
• Compact size

Electrical Characteristics:

• Input Voltage: 6.5V-15V
• 5V Output Capability: 550mA @ 9V and 350mA @ 12V
• 3.3V Output Capability: 400mA @ 9V and 275mA @ 12V
• Output Voltage Accuracy (under no load): 1%

Point of Difference:
Like the "regular" breadboard power supplies, the regulator chip has 1A current output capability. This capability is limited by the power dissipation capability of the cooling system.

For this reason, this power supply uses a TO-252 package rather than the low-cost SOT-223 package which is used in most breadboard power supply products.

Compared to the SOT-223 (plastic) package, the TO-252 package is bigger in size and has a metallic centre pad under the chip which dissipates heat much more efficiently. In addition, a copper thermal pad and multiple thermal vias are placed on the PCB below those regulator chips, which also helps to deliver heat to the atmosphere.

Package includes:

• A fully tested breadboard power supply module
• 2 aluminium heat sinks
• A 3M 8810 heat-conducting sticker (2.5cm x 2.5cm)
