Linear Technology Corporation (Milpitas, CA) introduces the LTC3807, a low quiescent current synchronous step-down DC/DC controller that draws only 50µA in standby mode with the output voltage in regulation. The 4V to 38V input supply range is designed to protect against high voltage transients, continue operation during automotive cold crank and cover a broad range of input sources and battery chemistries. The output voltage can be set from 0.8V to 24V at output currents up to 25 amps with efficiencies as high as 95%, making it well suited for automotive, heavy equipment, industrial and robotic applications. Other features include:
• 1.1 Ohm on-chip MOSFET gate drivers.
• Selectable fixed frequency between 50kHz and 900kHz.
• An external clock ranging from 75kHz to 850kHz.
