Micrel MIC2151
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.| Part No. | MIC2151 |
