Overview

MIC28303-1YMP-TR is synchronous step-down regulator module, featuring a unique adaptive ON-time control architecture. The module incorporates a DC/DC controller, power MOSFETs, bootstrap diode, bootstrap capacitor and an inductor in a single package. The MIC28303-1YMP-TR operates over an input supply range from 4.5V to 50V and can be used to supply up to 3A of output current. The output voltage is adjustable down to 0.8V with a guaranteed accuracy of ±1%. The device operates with programmable switching frequency from 200kHz to 600kHz.The MIC28303-1 uses HyperLight Load® architecture for improved efficiency at light loads. The MIC28303-2 uses Hyper Speed Control™ for ultra-fast transient response.The MIC28303-1YMP-TR offers a full suite of protection features. These include undervoltage lockout, internal soft-start, foldback current limit, 'hiccup' mode short-circuit protection, and thermal shutdown.
