Micrel MIC2174C
The Micrel MIC2174/MIC2174C is a fixed-frequency, synchronous buck controller featuring adaptive on-time control. The MIC2174/MIC2174C operates over an input supply range of 3V to 40V at a fixed switching frequency of 300kHz and is capable of driving 25A of output current. The output voltage is adjustable down to 0.8V.GENERAL DESCRIPTION
FEATURES
The output voltage is adjustable down to 0.8V. A unique Hyper Speed Control™ architecture allows for ultra-fast transient response while reducing the output capacitance. It also makes ultra-fast transient response while reducing the output capacitance and also allows for extremely low duty-cycle operation. The MIC2174 / MIC2174C utilizes an adaptive TON ripple controlled architecture. A UVLO is provided to ensure proper operation under power-sag conditions to prevent the external power MOSFET from overheating. A soft-start is provided to reduce inrush curren
