MIC2194YM-TR More Semiconductors - ICs by Microchip Technology
14V, 400 KHz Synchronous Buck Controller with 100% Duty Cycle and Programmable UVLO
| Status: | Active |
|---|---|
| Series: | MIC2194 |
| RoHS: | Compliant |
The MIC2194 solution saves valuable board space. The device is housed in the space-saving SO-8 package, whose low pin-count minimizes external components. Its 400kHz PWM operation allows a small inductor and small output capacitors to be used. The MIC2194 can implement all-ceramic capacitor solutions.
The MIC2194 drives a high-side P-Channel MOSFET. A low output driver impedance of 2ω allows the MIC2194 to drive large external MOSFETs to generate a wide range of output currents. The MIC2194 can achieve maximum duty cycles of 100%, which can be useful in low headroom applications.
The MIC2194 is available in an 8-pin SOIC package with a junction temperature range of -40°C to +125°C.
