Looking for a fmall footprint (122 mm2) high power (10W) boost regulator? Micrel announced the new series MIC2875 and MIC2876 2-MHz boost regulators.
They offer fixed output voltage of 4.75 V, 5.0 V, 5.25 V and 5.5 V, as well as an adjustable output voltage configuration, and they are capable to deliver up to 2A of current, with an efficiency of up to 95%. They suit well for single-cell lithium battery powered products.
These devices provide bidirectional power disconnection when disabled to prevent current from flowing back to the source. During low load operation, the switching frequency is reduced to extend the battery life (minimum 45 kHz).
