MIC2151YML-TR More Semiconductors - ICs by Microchip Technology
14.5V, Two Phase Synchronous Buck Controller IC, 300 KHZ
| Status: | Active |
|---|---|
| Series: | MIC2151 |
| RoHS: | Compliant |
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. The MIC2150/1 has a junction operating range from -40°C to +125°C.
