Introduction

AI Translation

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 RBuck 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.
