GENERAL DESCRIPTION
FEATURES
The MIC24420/MIC24421 are synchronous PWM dual output step down converters with internal 2.5A high-side switches. The MIC24420/MIC24421 has an integrated lowside gate driver for synchronous step-down conversion by connecting an external N-channel MOSFET to achieve high efficiencies in low duty-cycle applications. A patented control scheme allows the use of a wide range of output capacitance from small ceramic capacitors to large electrolytic types with only one compensation component. A 2% output voltage tolerance over the temperature range allows the maximum level of system performance. An adjustable current limit allows the use of smaller inductors in lower current appli
