DESCRIPTION
It RFEATURES
● Wide 4.5V to 28V Operating Input Range O● Programmable Switching Frequency from F 100kHz to 1.5MHz provides 3A output with current mode control for fast loop response and easy compensation. D The wide 4.5V to 28V input range accommodates a variety of step-down applications, including those in an automotive input environment. A E 100µA operational quiescent current allows use in battery-powered applications. D S High power conversion efficiency over a wide N 8 load range is achieved by scaling down the E N switching frequency at light load condition to 3 reduce the switching and gate driving losses. M IG 3 The frequency foldback helps prevent inductor current runaway during startup and thermal 2 shutdown provides reliable, fault tolerant M S operation. C O The MP1584 is available in a thermally enhanced SOIC8E package. RE EW T TYPICAL APPLICATION R C4 100nF T N E 8 O F VIN 7 VIN BST SW 1 D1 N RE EN 2 EN FB 4 MP1584 EFFICIENCY (%)
