MIC4684YM-TR Description

Short technical summary and product information.

The MIC4684YM-TR is a 2A high-efficiency SuperSwitcher buck regulator designed by Micrel. It provides power conversion efficiency of over 85% and achieves 2A of continuous current in an SO-8 package. This device is suitable for applications requiring a simple, high-efficiency step-down regulator.

The regulator features a wide input voltage range of 4V to 30V with a 34V transient capability, making it robust for various power environments. The output voltage is adjustable down to 1.235V. Built-in safety features include over-current protection, frequency-foldback short-circuit protection, and thermal shutdown, enhancing system reliability.

With its fixed 200kHz PWM operation and internally compensated design for fast transient response, the MIC4684YM-TR is well-suited for on-card switching regulation. Its SO-8 package eliminates the need for external heat sinks in many applications, allowing for compact, all surface-mount solutions.

Typical applications include 5V to 3.3V converters, 12V to 1.8V converters, and battery chargers. The device operates within a junction temperature range of -40°C to +125°C.
