The LM5017 is a 600 mA constant on-time synchronous buck regulator with built-in high side and low side MOSFETs. This device has a wide input voltage range from 7. 5 V to 100 V. The constant on-time control scheme used in this device doesn’t need loop compensation, delivers excellent transient response, and enables very high […]

Operational amplifiers (OPAMPs) are high performance differential amplifiers in integrated form that can be used in many different ways. A typical OPAMP has a non-inverting input, an inverting input, two dc power pins, one output pin and a few other fine-tuning pins. On the following image you can see a typical diagram of an operational

Overview Trinket lends itself very well to building clock projects, its small and easy to hide behind a larger display. And clocks don’t need a lot of logic, this example only has maybe 20 lines of code. Adding a digital display via I2C is possible using seven segment or character-based displays (with the library code
