The SGM61450 is a current mode controlled non-synchronous 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. 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 SGM61450 is available in a Green SOIC-8 (Exposed Pad) package.
