SGM61450 - 5A Buck Converter

Key Features

  • The SGM61450 is a current mode controlled nonsynchronous Buck converter with 4.5V to 42V input range and 5A continuous output current. A low RDSON N-MOSFET is integrated as high-side switch. The quiescent current is as low as 148μA. The shutdown current drops to 2.75μA during shutdown (EN = low). The internal under-voltage lockout (UVLO) threshold is 4.2V and can be adjusted (increased) by an external resistor divider. An internal soft-start circuit controls the output voltage start-up ramp.

SGM61450 4.5V to 42V Input, 5A Buck Converter GENERAL DESCRIPTION FEATURES The SGM61450 is a current mode controlled nonsynchronous Buck converter with 4.5V to 42V input range and 5A continuous output current. A low RDSON N-MOSFET is integrated as high-side switch. The quiescent current is as low as 148μA. The shutdown current drops to 2.75μA during shutdown (EN = low). The internal under-voltage lockout (UVLO) threshold is 4.2V and can be adjusted (increased) by an external resistor divider. An internal soft-start circuit controls the output voltage start-up ramp. Switching frequency can be selected over a wide range (100kHz to 2500kHz) to allow desired tradeoff among efficiency, component sizes and conversion voltage ratio.
