This is a Tibbit module — part of the Tibbo Project System that allows you to build your own custom embedded device with only the components you need. Start with a Tibbo Project PCB, add Tibbits like this one, then place the built design into a Tibbo Project Box to complete your product.
Tibbit #09: Low-power non-isolated power supply with 5V output, 9-18V input range, shutdown control.
This Tibbit is capable of generating up to 450mA of 5V power from an external input in the 9-18V range. Multiple power-supply Tibbits can be used to increase available current or for power redundancy.
Combine this Tibbit with a C Tibbit #18 (power jack and two terminal blocks), #20 (nine terminal blocks), or #21 (four terminal blocks).
There are two LEDs. The green LED is connected to the +5V output and lights up when the voltage is present on this line. The red LED is connected to the SHUTDOWN line and lights up when the line is LOW (i.e. when the power supply is in shutdown). The red LED is buffered (with a logic gate).
- Form: M1S
- Power: 5V output; provides 450mA
- Mates with: #18, #19, #20, #21
- Similar to: #10, #12, #22, #23
M1S Tibbit Modules Overview M1S Tibbits are single-width modules occupying one standard M socket on a Tibbo Project PCB (i.e. TPP2 or TPP3). Their footprint is roughly 7 × 14 "squares" (one "square" is 2.54 × 2.54 mm). The M1S modules are 12.5mm high.
M1 modules have two rows of 6 pins:
Pins 8-11 are control lines A-D. They provide the interface to programmable modules or other microcontrollers. On Tibbo Project PCBs, these pins are connected to the main processor.
Pins 2-5 are I/O lines facing the outside world. On Tibbo Project PCBs, they go to C Tibbits.
Pins 6 and 12 are the GROUND and +5V power pins. Most Tibbit Modules consume (take) 5V power. There are also power supply Tibbits that generate 5V power from a variety of sources. Those output 5V through pin 12.
Pins 1 and 7 are for the additional +15V and -15V voltages. These are optional and only needed by few Tibbits. A special power supply Tibbit (#12) generates ±15V from the main 5V power.
