SGM61432
40V/3.5A, Adjustable Switching Frequency Buck Converter with 38μA I<sub>Q<sub>
The SGM61432 is a current mode controlled non-synchronous Buck converter with 4V to 40V input range and 3.5A continuous output current. A low RDSON N-MOSFET is integrated as high-side switch. Moreover, the low 38μA quiescent current and low shutdown current of only 1.3μA (TYP) make it a suitable choice for battery-powered applications. Also, the internal loop compensation simplifies compensation network design and saves user design time and cost. The UVLO level can be adjusted (increased) by an external resistor divider. Switching frequency can be selected over a wide range (200kHz to 2500kHz) to allow desired tradeoff among efficiency, component sizes and conversion voltage ratio. 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 SGM61432 is available in a Green SOIC-8 (Exposed Pad) package.
