Buck 2 click is a powerful step down DC-DC switching regulator. It gives a high precision regulated voltage at its output and it can handle an ample amount of current. Buck 2 click is highly configurable - the output voltage, maximum current limiting, and the switching frequency parameters can be controlled via the IC pins routed to the mikroBUS™ socket, providing a simple and secure connection to the host MCU.
The input voltage can range from 4.5V to 19V and the output can be set to work in several discrete steps, ranging from 0.7V to 3.3V. Features, such as the wide range of input voltages, pin configurable working parameters, internal soft start, thermal shutdown, hiccup mode short-circuit protection and high switching efficiency, make this device a perfect choice for any step-down application which demands reasonably high current and accurate voltage regulation with clean and ripple-free low voltage power supply - such as the embedded electronic devices, servers, routers, data storage devices, low power ICs and similar.
Buck 8 click is a high efficiency, wide voltage range, and high current synchronous step down (buck) DC-DC converter, featuring two enhanced modes that can be used to drive lighter loads with increased efficiency. The output voltage can be adjusted by the multi-turn trimmer potentiometer. Since the output voltage is set mechanically, it will retain the set value, even after the restart. Very high efficiency results with the reduced power dissipation, thus allowing reasonably high power to be delivered to the load, connected to the output terminal. Internal feedback compensation across the whole voltage range allows lower number of external components.
Opto 2 click is a galvanic isolator Click board™, used to provide an optical isolation of sensitive microcontroller (MCU) pins, when operated by external signals. TLP2770 opto-isolation elements (optocouplers) can be driven with a very low current, down to 1.3mA (min). A choice of high-speed optocouplers allows Opto 2 click to be used on communication lines, with up to 20 Mbps data rates. This Click board™ can be used to provide an optical isolation when there is a requirement for a high reinforced isolation between the external signal lines and the controller logic with a MCU such as in PLCs or similar applications
