SGM61630 60V, 3A Buck Converter with 50μA IQ
GENERAL DESCRIPTION
Features
The SGM61630 is a current mode controlled Buck regulator with 4.3V to 60V input range and 3A continuous output current. The device suits various applications of industry, which demands power conditioning from unregulated sources. A 140mΩ RDSON MOSFET is integrated as high-side switch. The ultra-low 50μA (TYP) quiescent current and low shutdown current of only 2μA (TYP) make it a suitable choice for battery-powered applications. Switching frequency can be selected over a wide range (200kHz to 2500kHz) to allow desired tradeoff between efficiency and ponent sizes. There is also the internal loop pensation that simplifies pensation network design, and requires less external ponents, saving user design time and cost. With precision enable input, regulator control is simplified, as well as system power sequencing. Protection against over-voltage transient is provided to limit the startup or other transient overshoots. Secure operation in overload conditions is ensured by thermal shutdown protection and cycle-bycycle current limit.
The SGM61630 is available in a Green SOIC-8 (Exposed Pad) package.
