SGM61103

3V to 17V, 300mA Buck Converter with

Adjustable Enable Threshold and Hysteresis

GENERAL DESCRIPTION

FEATURES

The SGM61103 is an easy-to-use synchronous Buck

DC/DC converter optimized for low-power applications.

A high switching frequency of 1MHz (TYP) allows the

use of small inductors and provides fast transient

response as well as high output voltage accuracy by

using AHP-COT control topology.

● AHP-COT Control Topology

● Input Voltage Range: 3V to 17V

● Output Voltage Range: 1.2V to 10V

● Quiescent Current: 28µA (TYP)

● Shutdown Current: 450nA (TYP)

● Switching Frequency: Up to 1MHz

● EN Pin with Precise Threshold

● EN_HYS Pin for Additional Hysteresis

Programming

With its wide operating input voltage range of 3V to 17V

and low quiescent current, SGM61103 is ideally suited

for battery-powered systems. The SGM61103 works in

power-save mode to ensure the highest efficiency at

light load conditions.

● 100% Duty Cycle Mode

● Power Good Indicator

● Output Discharge

The SGM61103 supports up to 300mA continuous

output current at wide output voltages between 1.2V

and 10V. Lower-power EN comparator with precise

threshold and hysteresis can be used as the input

supply voltage supervisor (SVS). More hysteresis is

possible by combining with EN_HYS pin. PG pin is also

provided as output voltage indicator.

● Available in a Green TDFN-2×2-8AL Package
