SGM6021

400nA Ultra-Low Power, Buck Converter

with 200mA Output Current

GENERAL DESCRIPTION

FEATURES

The SGM6021 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.

● Input Voltage Range: 1.8V to 5.5V

● Output Voltage Programmable in Operation

● High Efficiency at Low Output Currents:

Up to 90% with I_OUT= 0.1mA

● Ultra-Low Power Buck Converter

● 200mA (MAX) Output Current

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.

● 400nA (TYP) Quiescent Current

● 100% Duty Cycle (Pass Mode)

● -40℃ to +85℃ Operating Temperature Range

● Available in a Green UTDFN-1.5×2-6L Package

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,

C_INand C_OUTcapacitors are needed as external

components to make a Buck DC/DC converter solution.
