Expanding Semtech’s POL regulator offerings is the highly-integrated, 4A-output SC185 synchronous buck regulator with programmable soft-start in a 3 mm x 3 mm x 0.6 mm package. The device allegedly simplifies power-supply design by integrating the regulator, loop compensation components, power MOSFETs, and MOSFET drivers on one chip. Additionally, this level of integration eliminates the need for external loop stabilization components and programming resistors. Price is $1.60 each/3,000.
