MP1584
DESCRIPTION
The MP1584 is a high frequency step-down switching regulator with an integrated internal high-side high voltage power MOSFET. It
R FEATURES
- Wide 4.5V to 28V Operating Input Range
- Programmable Switching Frequency from F 100k Hz to 1.5MHz provides 3A output with current mode control for fast loop response and easy pensation.
D The wide 4.5V to 28V input range acmodates 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. P By switching at 1.5MHz, the MP1584 is able to E prevent EMI (Electromagnetic...
