MP1584EN
Overview
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 O Programmable Switching Frequency from F 100kHz to 1.5MHz provides 3A output with current mode control for fast loop response and easy compensation.
- 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.
- 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.
- 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 Interference) noise O M problems, such as those found in AM radio and
- ADSL applications. C O The MP1584 is available in a thermally enhanced SOIC8E package.
