MIC2155規(guī)格書詳情
General Description
The MIC2155 and MIC2156 are a family of two-phase, single-output synchronous buck control ICs featuring small size, high efficiency, and a high level of flexibility. The ICs implement a 500kHz (MIC2155) and 300kHz (MIC2156) voltage mode PWM control, with the outputs switching 180° out of phase. The result of the out-of-phase operation is 1MHz (or 600kHz) input ripple 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.

? 300kHz PWM operation (MIC2156)
? Adaptive gate drive allows efficiencies over 95
? Adjustable current limit with no sense resistor
? Senses low-side MOSFET current
? Internal drivers allow 25A per phase
? Power Good output allow simple sequencing
? Dual enables with micro-power shutdown and UVLO
? Programmable soft-start pin
