L6983IQTR General Description
The L6983I is a highly specialized device tailored for isolated buck topology, offering precise adjustment of the primary output voltage and a secondary output derived through transformer ratio, eliminating the need for an optocoupler. With a primary sink capability of up to -4.5 A, energy transfer to the secondary side is optimized, and a tracked soft-start of the secondary output is enabled. Operating on a peak current mode architecture, this device functions in forced PWM mode with a 390 ns blanking time to filter out oscillations caused by transformer leakage inductance, enhancing robustness. The compact QFN16 3x3 mm package and internal compensation simplify design complexity and size. Additionally, users can program the switching frequency in the 200 kHz - 1 MHz range, with optional spread spectrum for improved EMC. The EN pin allows for enable/disable functionality, with a low shutdown current of 2 μA when disabled, and a swift 1.3 ms soft-start upon re-enabling. A Power Good open collector monitors the FB voltage, while pulse by pulse current sensing and thermal shutdown offer effective constant current protection and prevent thermal run-away
