The SGM61232 is a current mode controlled non-synchronous Buck converter with 4V to 28V input range, 3A rated output current and adjustable output voltages from 0.8V up to 25V. A low RDSON N-MOSFET is integrated as high-side switch. Pulse-skip mode (PSM) feature is activated automatically for power-save mode at light loads to improve efficiency. Because of its low shutdown current (1.2μA, TYP), this device can be used in battery operated applications. The internal current mode controller with slope compensation allows ceramic capacitors at the output and simplifies compensation network design. The UVLO level can be adjusted (increased) by an external resistor divider. Protection against over-voltage transient is provided to limit the startup or other transient overshoots. Secure operation in overload conditions is ensured by cycle-by-cycle current limit, frequency fold-back and thermal shutdown protection.
The SGM61232 is offered in Green SOIC-8 (Exposed Pad) and SOIC-8 packages. The device can operate in the -40℃ to +125℃ ambient temperature range.
