The TC427CPA is a 1.5A dual high-speed power MOSFET Driver for use with pulse transformer drive. TTL/CMOS input voltage level is translated into a rail-to-rail output voltage level swing. The CMOS output is within 25mV of ground or positive supply. The low-impedance, high-current driver outputs swing a 1000pF load 18V in 30ns. The unique current and voltage drive qualities make the TC427 ideal power MOSFET drivers, line drivers and DC-to- DC converter building blocks. Input logic signals may equal the power supply voltage. Input current is a low 1μA, making direct interface to CMOS/bipolar switch-mode power supply control ICs possible, as well as open-collector analog comparators. Quiescent power supply current is 8mA maximum. The TC426 requires 1/5 the current of the pin-compatible bipolar DS0026 device. This is important in DC-to-DC converter applications with power efficiency constraints and high-frequency switch-mode power supply applications.
