The MAX1626ESA+T with Switching Controllers 5V/3.3V or Adjustable, 100% Duty Cycle, High-Efficiency, Step-Down DC-DC Controllers is a component manufactured by Analog Devices. This device can be used to convert unregulated DC power inputs into regulated DC output voltages, within a precise range, utilising high-efficiency switching technology. The MAX1626ESA+T is capable of providing 5V, 3.3V or adjustable outputs depending on the application requirements, and the 100% Duty Cycle rating ensures smooth transitions and minimal power losses. The high-efficiency of the device enables power consumption savings of up to 8% compared to similar controllers, and a high-side NFET allows for additional savings of up to 10%. The device includes a range of protection features, such as thermal shutdown, adjustable current or voltage limit and short-circuit protection, and is housed in a small 6-pin SOT-23 package to maximize space savings. It is suitable for a range of applications, including external hard drives, personal digital assistants, display backlighting, low power microprocessor/microcontrollers, and gaming consoles.
