Status: In Production
The MIC2198 is a high power 500kHz synchronous buck DC-to-DC controller. The MIC2198 operates from a wide 4.5V to 32V input and can be programmed for output voltages from 0.8V to 6V. The wide input voltage capability makes the MIC2198 an ideal solution for point-of-load DC-to-DC conversion in 5V, 12V and higher systems. The 500kHz switching frequency allows the use of a small inductor and small output capacitors. The current mode PWM control along with the external COMP pin allows for ease of stability compensation and fast transient response across a wide range of applications. An all N-Channel synchronous architecture and powerful output drivers allow up to 20A of output current capability. For higher efficiency at higher input voltages, refer to the 300kHz MIC2199. The MIC2198 is available with a junction temperature range from -40°C to 125°C.
