GENERAL DEscriptION

The SGM6021 family is a 200mA, 1.4MHz synchronous Buck DC/DC converter with 400nA ultra-low current, which is ideal for powering ultra-low power applications with special needs.

The SGM6021 operation voltage range is from 1.8V to 5.5V, allowing the use of a regulated 5V input. The output regulator levels are programmed through VS pin and can be programmed for 4 different voltages, making it ideal for designing device with limited power budget calculation.

The SGM6021 delivers an output current of 200mA with a peak inductor current of 430mA. Besides, the SGM6021 series has the under-voltage lockout (UVLO) function. It is disabled when the voltage on VIN reaches the UVLO condition. The SGM6021’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 SGM6021 is available in a Green UTDFN-1.5×2-6L package.
