Datasheet Details

Part number	MIC2151, MIC2150
Manufacturer	Micrel Semiconductor
File Size	725.92 KB
Description	2-Phase Dual Output PWM Synchronous Buck Controller
Datasheet	MIC2150-MicrelSemiconductor.pdf
Note	This datasheet PDF includes multiple part numbers: MIC2151, MIC2150. Please refer to the document for exact specifications by model.

The MIC2150/1 are simple 2-phase dual-output synchronous buck control ICs featuring small size and high efficiency. The ICs implement PWM control at 500kHz (MIC2150) or 300kHz (MIC2151), with the outputs switching 180° out of phase. The result of the out-of-phase operation is 1MHz input ripple frequency with ripple current cancellation, minimizing the required input filter capacitance. A 1% output voltage tolerance allows the maximum level of system performance. Internal drivers with adaptive g.
