The MIC2267YML-TR from Microchip Technology is a USB Power Maximizer™ synchronous buck regulator. It is designed to transfer maximum power from limited USB current sources by shaping the input current limit profile. This integrated synchronous step-down regulator incorporates internal 150mΩ switches and offers an adjustable operating frequency.
Key electrical specifications include an input voltage range of 3.0V to 5.5V and an adjustable output voltage down to 1.0V. It can deliver up to 500mA of output current with efficiencies exceeding 90% across a broad load range, reaching up to 96% at 500mA output. The switching frequency is adjustable from 400kHz to 1.5MHz, allowing for harmonic management.
Additional features include micropower shutdown (1µA), thermal shutdown protection, and output current limit protection. The device operates within a junction temperature range of -40°C to +125°C. It is housed in a 12-pin 3mm x 3mm MLF® package, suitable for surface mounting.
This regulator is ideal for USB power applications, wireless router cards, and general buck converter designs where efficiency and flexible input current limiting are critical.
