Overview

The A6986I is an automotive grade device specifically designed for the isolated buck topology. The 100% duty cycle capability and the wide input voltage range meet the cold crank and load dump specifications for automotive systems. The primary output voltage can be accurately adjusted, whereas the isolated secondary output is derived by using a given transformer ratio. No optocoupler is required. The primary sink capability typically up to 1.9 A (even during soft-start) allows a proper energy transfer to the secondary side as well as enabling a tracked soft-start of the secondary output. The control loop is based on a peak current mode architecture and the device operates in forced PWM. The 300 ns blanking time filters oscillations, generated by the transformer leakage inductance, making the solution more robust. Pulse-by-pulse current sensing on both power elements implements an effective constant current protection in the primary side. Due to the primary reverse current limit, the secondary output is protected against short-circuit events. A primary output voltage supervisor, which notifies primary output voltage regulation through the RST open collector output, overvoltage protection, adjustable switching frequency, synchronization and a programmable soft-start are also available. For traditional buck topology in automotive application the A6986 / A6985F / A6986F / A6986H is recommended.
