SGM61450

4.5V to 42V Input, 5A Buck Converter

GENERAL DESCRIPTION

FEATURES

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 R_DSON

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.
