Converter packs internal 60 V power switch
With an on-resistance of 100 mΩ, the converter’s internal 4 A, 60 V power switch achieves efficiencies of over 95%. It also offers spread spectrum frequency modulation to minimize EMI concerns. A single feedback pin sets the output voltage, whether the output is positive or negative.
Switching frequency of the LT8364 is programmable between 300 kHz and 2 MHz and efficiency is over 90% when switching at 2 MHz. Burst-mode operation reduces quiescent current to just 9 µA, while keeping output ripple below 15 mV pk-pk.
The LT8364 is available in industrial and high-temperature versions. Packaging options include a 4×3-mm, 12-lead plastic DFN and a 16-lead plastic MSOP with 4 pins removed for high-voltage spacing. Prices for the DC/DC converter start at $3.25 each in lots of 1000 units.
