New products: 3.3V, 5V, 6V, 7.5V, and 9V Step-Down Voltage Regulator D24V22Fx

This post is a few weeks late, but I am following up on my original D24V22F12 12V regulator introduction to let you know that we now have 3.3 V, 5 V, 6 V, 7.5 V, 9 V, and 12 V versions of our new D24V22Fx family of step-down voltage regulators. These regulators all have typical efficiencies of 85% to 95% and can deliver continuous currents over 2 A in typical applications.

The new D24V22Fx regulators are priced lower than the older D24V25Fx family that they will be replacing. The two designs have the same size and similar current capabilities and input voltage ranges, but they do not have the same pinout and are based on different internal circuits, so there are fundamental differences in operation. In particular, these newer D24V22Fx regulators have much lower dropout voltages and provide a “power good” signal, and the newer design allows for higher output voltages (e.g. 12 V).

See the product pages for any of the D24V22Fx regulators for more information on these new regulators, or visit our voltage regulator category to see all of our regulator options.

New product: Ion Motion Control RoboClaw 2x7A dual motor controller (V5)

New product: Ion Motion Control RoboClaw 2x7A dual motor controller (V5)

The RoboClaw motor controllers from Ion Motion Control (formerly Orion Robotics) can control a pair of brushed DC motors using USB serial, TTL serial, RC, or analog inputs. Integrated dual quadrature decoders make it easy to create a closed-loop speed control system.

Ion Motion Control has replaced the MOSFETS on the RoboClaw 2x5A Motor Controller (V5) with better ones and is now calling it the RoboClaw 2x7A Motor Controller (V5). The 2x7A can supply up to 7.5 A continuous and 15 A peak, up from 5 A and 10 A, and is otherwise functionally and physically identical to the 2x5A.

More details are on the RoboClaw 2x7A Motor Controller (V5) product page.

New big MOSFET-based power switches

Our mini MOSFET-based power switches now have a set of companion versions with larger MOSFETs:

As I mentioned when announcing the Mini switches in September, they have many advantages over our older pushbutton power switches, including a much larger input voltage range and reverse protection, but the current limits were lower. With the new big switches, we can now support applications well beyond what the older products could handle. We are offering two versions with different MOSFETS: the MP unit can handle about 8 A, and the HP version is good for about 16 A. Both operate over the same 4.5 V to 32 V range as the Mini SV switches.

Like the mini power switches, these big switches are available with our patented push-on/push-off latching circuit or with a simple slide switch:

Big Pushbutton Power Switch with Reverse Voltage Protection, MP.
Big MOSFET Slide Switch with Reverse Voltage Protection, HP.

For more information, see the links below or check out our power switch category.

Kevin's mini-sumo robot: Roku

Kevin's mini-sumo robot: Roku

My robot, Roku, was the champion of LVBots’ August mini-sumo competition. While I didn’t have the time or inspiration to make it look like anything more interesting (like a Star Wars droid) or make use of especially innovative tactics, I think I managed to build a robot that not only is effective but also looks fairly clean and well put together. In addition, it’s a good demonstration of how the Pololu A-Star 32U4 Robot Controller can be used as a standalone main board for a small robot. Continued…
