MIC2151 - 2-Phase Dual Output PWM Synchronous Buck Controller

Download the MIC2151 datasheet PDF. This datasheet also covers the MIC2150 variant, as both devices belong to the same 2-phase dual output pwm synchronous buck controller family and are provided as variant models within a single manufacturer datasheet.

Key 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 g.

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.
