Tiny boost regulators deliver up to 10 W

Offered with fixed output voltages of 4.75 V, 5.0 V, 5.25 V and 5.5 V or an adjustable output voltage, the MIC2875 and MIC2876 2-MHz boost regulators from Micrel are capable of supplying up to 2 A of output current, while occupying just 122 mm2 of board space. These synchronous regulators also achieve efficiency of up to 95% and are well-suited for operation from a single-cell lithium battery and providing power to applications such as USB on-the-go and HDMI hosts, tablets, and smart phones.

The low-profile devices offer bidirectional load disconnect to prevent current flow between input and output when the regulator is disabled. Under light loads, the parts reduce the switching frequency to extend battery life. Other features include bypass mode operation when the input voltage exceeds the set output voltage and an anti-ringing switch to minimize EMI issues during discontinuous mode.
