MP2303ADN-LF-Z Rectifier Buck Converter
MP2303ADN-LF-Z
3A, 28V, 360KHz synchronous rectification step-down converter
Product Description
The MP2303A is a monolithic synchronous buck regulator. The device integrates a 150MΩ high-side MOSFET and an 80MΩ low-side MOSFET to deliver 3A continuous load current over a wide operating input voltage range of 4.7V to 28V. Current-mode control provides fast transient response and cycle-by-cycle current limiting. Adjustable soft-start prevents inrush current at turn-on. In shutdown mode, the supply current drops below 1µA. Available in 8-pin SOIC and PDIP-8 packages, the device provides a very compact system solution with minimal dependencies on external components
