May 27, 2015 – Mouser Electronics, Inc., the global authorized distributor with the newest semiconductors and electronic components, is now stocking Micrel MIC28303 Power Modules. The MIC28303 modules from Micrel are synchronous step-down regulator modules that feature a unique adaptive ON-time control architecture.
The 50V 3A Micrel MIC28303 Power Modules, available from Mouser Electronics, combine a DC/DC controller, power MOSFETs, bootstrap diode, bootstrap capacitor, and an inductor—all in a single package. The MIC28303 modules feature a 4.5V to 50V supply range, with adjustable output voltage from 0.9V to 24V (limited by duty cycle). The modules can supply up to 3A of output current and are adjustable down to 0.8V with a guaranteed accuracy of ±1%. The ON-time control architecture allows for a constant switching frequency, programmable between 200kHz and 600kHz.
The MIC28303-1 module uses Micrel’s HyperLight Load architecture for improved efficiency at light loads. The MIC28303-2 module uses Micrel’s Hyper Speed Control for ultra-fast transient response. Both modules offer a full suite of protection features, including under voltage lockout, internal soft-start, foldback current limit, “hiccup” mode short-circuit protection, and thermal shutdown.
The Micrel MIC28303 step-down regulator DC/DC converters feature low-radiated emissions, power-good signaling, and a junction temperature range of -40°C to +125°C, making them ideal for industrial and medical applications.
