Available in H- and MP-grade versions with operating junction temperatures from -40°C to 150°C and -55°C to 150°C, respectively, the LTC3853 triple output synchronous step-down switching regulator controller operates over a 4.5V to 24V input voltage range. It can produce output currents up to 20A per phase with output voltages ranging from 0.8V to 13.5V at up to 95% efficiency. Other features include a precision 0.8V reference with an accuracy of ±1.25% over a -55°C to 150°C operating temperature range. With up to 98% duty cycle, the device has a very low dropout voltage. Available in a thermally enhanced 6 mm x 6 mm QFN-40 package. Pricing $4.24 each/1,000. A datasheet is available at http://cds.linear.com/docs/en/datasheet/3853fb.pdf
