1.2x1.2x0.3mm measuring 600mA Step-Down DC/DC Converter
Date: 27/10/2023
Very tiny new stepdown DC DC converter from Torex semiconductor measures 1.2x1.2x0.3mm, providing the world's smallest solution size, including peripheral components.
The buck synchronous rectification DC/DC converter XC9290/XC9291 series features HiSAT-COT control offering faster response compared to conventional PWM control, due to which this require smaller ceramic capacitor of size around 0.6x0.3mm and also uses smaller size inductor just measuring 1.0x0.5mm, resulting in overall reduction in size . XC9290/XC9291 series improves the oscillation frequency variation due to output current changes and the output voltage variation (load stability), resulting in more user-friendly and stable control.
XC9290/XC9291 series provide the option to choose from two high oscillation frequencies, 4MHz and 6MHz. Even at 4MHz, it achieves 90% efficiency with 3.7V input and 1.8V output voltage, contributing to extended battery life and reduced heat generation (see figure below). Therefore, it is an ideal product for all small devices, including modules and sensors, regardless of whether they are used in consumer or industrial applications, where space-saving is essential.
The device also features low EMI and low ripple, making it suitable for small and densely packed electronic devices. It has minimal impact on peripheral devices in high-density mounting, and the radiation noise from the device is extremely low. See figure below.
XC9290/XC9291 also features a fast transient response as shown in the figure below:
