XC9290/91: World's Smallest DC/DC Converter
Optimisation of the PCB Surface With TOREX
TOREX, recognised for its expertise in compact power solutions, introduces the XC9290/91, the world's smallest step-down DC/DC converter. This versatile solution finds applications in a diverse range of uses, meticulously crafted to optimise spatial efficiency and elevate the aesthetics and functionality of products such as wireless earbuds, VR headsets, trackers, medical monitoring devices, camera modules, wireless modules and miniature sensors.
Need for Compact Solutions
The escalating demand for diminutive integrated circuits (ICs) and the imperative to minimise the mounting area for accommodating compact products have emerged as pivotal factors across various industries. This trend is particularly pronounced in products like discreet in-the-ear hearing aids, underscoring the necessity for innovative and compact solutions.
The XC9290/91 stands out as an ultra-small size solution, requiring a mere PCB mount area of 3.15mm². This makes it an ideal choice for designers seeking compact solutions. Leveraging HiSAT-COT Control Technology, the XC9290/91 ensures ultra-fast load transient response performance while maintaining a stable switching frequency. Consequently, hearing aids powered by the XC9290/91 deliver superior performance, even when utilising ultra-small 0603 ceramic capacitors. The XC9290/91 is distinguished as a low EMI & low noise solution, a critical feature for noise-sensitive applications like hearing aids. Notably, it complies with EN55032 (CISPR 32) CLASS B standards.
Examining the DC/DC specifications, the XC9290/91 delivers an output current of 600mA within an input voltage range of 2.5V to 6.0V and output voltage range of 0.7V to 3.6V. The selectable switching frequency ranges from 4.0MHz to 6.0MHz.
