Product Introduction
The MIC2198 is a high-power 500kHz synchronous buck DC-to-DC controller housed in a small 4mm × 4mm MLF 12-pin package. 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.
The MIC2198 is available in a 12-pin 4mm × 4mm MLF package with a junction temperature range from -40°C to 125°C.
