M3tek – MT3102: Synchronous Buck Converter

The MT3102, with a switching frequency of up to 2.5 MHz, helps reduce the size of peripheral components such as inductors and capacitors, making the overall design more compact. The IC operates with an input voltage range from 2.5V to 6V and provides a minimum output voltage of 0.6V, thanks to its 100% duty cycle operation, which optimizes efficiency under various load conditions.

Additionally, the continuous on-time control scheme enables loop compensation and provides fast transient response. The MT3102 consumes an ultra-low quiescent current of only 15µA, achieving excellent light-load efficiency and extending battery life. With an efficiency of up to 95%, the MT3102 helps save energy and reduce operating temperatures, making it suitable for various applications such as SSDs, RF Wi-Fi modules, smartphones, and tablets.
