Product Overview
STEVAL-A6983IV1 is an evaluation board based on the A6983I, 38V, 10W synchronous iso-buck converter designed for isolated applications. 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 up to -4.5A (even during soft-start) allows a proper energy transfer to the secondary side as well as enables 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 390ns blanking time filters oscillations, generated by the transformer leakage inductance, making the solution more robust. The compact QFN-16 3x3mm package and the internal compensation of the A6983I help minimizing design complexity and size. The switching frequency can be programmed in the 200kHz - 1MHz range with optional spread spectrum for improved EMC.
