Ultra-Low Quiescent Current, Synchronous Buck Converter
The SGM6031 family is a 200mA, 1.4MHz synchronous buck DC/DC converter with 400nA ultra-low quiescent current, which is ideal for powering ultra-low power applications with special needs.
The SGM6031 operation voltage range is from 1.8V to 5.5V, allowing the use of a regulated 5V input. The SGM6031 is available in both adjustable and fixed output voltage versions. The output voltage of SGM6031 can be programmed by an external resistor divider in adjustable version.
The SGM6031 delivers an output current of 200mA with a peak inductor current of 430mA. Besides, the SGM6031 series has the under-voltage lockout (UVLO) function. It is disabled when the voltage on VIN reaches the UVLO condition. The SGM6031’s under-voltage lockout level is continuously monitored. Only inductor, CIN and COUT capacitors are needed as external components to make a Buck DC/DC converter solution.
The SGM6031 is available in a Green UTDFN-1.5×2-6L package.
