Product Summary
The MP1482DS is a monolithic synchronous buck regulator. The device integrates two 130mW MOSFETs, and provides 2A of continuous load current over a wide input voltage of 4.75V to 18V. Current mode control provides fast transient response and cycle-by-cycle current limit. An adjustable soft-start prevents inrush current at turn-on, and in shutdown mode the supply current drops to 1 μA. The MP1482DS, available in an 8-pin SOIC package, provides a very compact solution with minimal external components. `
