Four best below 1-A DC-DC converter Ics for wearbles and smart IoT

Except you have a highly regulated constant DC Power bus, in all other cases you need a DC DC converter IC, or a direct AC/DC converter IC in every electronic systems you design. And further for some ICs and circuit blocks on printed circuit board with different voltage requirements you may also need some stand-alone DC/DC converters or low dropout linear regulators. Along with the voltage and current ratings, the most important thing you look while selecting DC DC converter IC is power conversion efficiency. For compact and portable electronic systems the size of the device also matters. However the range of other specifications and functionalities you seek in selecting the dC-DC converter include external components required, noise performance, switching speed, quiscent current, harsh weather withstanding ability, and safety and protection features. Let's look at some of the buck type DC -DC converters with in the current range of less 1 A recently released in the market for space and power constrained applications such as wearables and any such tiny portable electronics including smart IoT. 1. XCL232 Low Power Step-Down Micro DC/DC: The XCL232 from Torex offers a low Quiescent current of 200 Na and offers a power efficiency of above 80% even at low output currents. XCL232 takes a PCB space of 2.5 mm x 2.0 mm and a height of 1.04 mm. This device does not require e...
