Optimised for isolated buck regulator designs, the STMicroelectronics A6986I and L6986I DC/DC converter ICs have a wide input voltage range and low quiescent current to ensure robust and energy-efficient operation in automotive and industrial applications up to 5 W.
The isolated buck topology lowers the bill of material in systems that require a regulated, non-isolated primary voltage and one or more isolated secondary voltages. The secondary voltage is governed by the transformer turns ratio and no optocoupler is needed for regulation. Common uses include powering gate drivers for SiC MOSFETs and IGBTs that require asymmetrical isolated power rails and powering isolated interfaces such as RS-232, I2C and SPI.
Typical applications for the AEC-Q100 Grade-1 qualified A6986I converters include automotive on-board chargers and hybrid/electric-vehicle traction drives. The industrial-grade L6986I is ideal in motor drives, solar power conditioning systems, uninterruptible power supplies (UPS) and welders.
The devices feature programmable soft-start to enhance reliability and pulse-by-pulse current sensing for constant-current protection on the primary side. A preset current-sense blanking time of 300 ns filters oscillations generated by the transformer leakage inductance and ensures greater stability during high-side switching transitions.
