MIC24421 - 2.5A Dual Output PWM Synchronous Buck Regulator IC

Download the MIC24421 datasheet PDF. This datasheet also covers the MIC24420 variant, as both devices belong to the same 2.5a dual output pwm synchronous buck regulator ic family and are provided as variant models within a single manufacturer datasheet.

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.

MIC24420/MIC24421 2.5A Dual Output PWM Synchronous Buck Regulator IC 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. The MIC24420 switching frequency is 1MHz and the MIC24421 switching frequency is 500kHz. 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.
