Overview
MIC2150/MIC2151 2-Phase Dual Output PWM Synchronous Buck Control IC General Description Features 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 gate drive allow the highest efficiency with the minimum external components.
A dual threshold enable pin, matched soft-start pins, and a power good output are provided, allowing a high level of control.
