168F1 series planar flyback transformers for no-opto boundary-conduction-mode designs built around the LT8302 and LT8304 controllers. Sampling the primary winding removes the opto-isolator and its tolerance stack, giving tight output regulation across the full input range. Same 16 × 16 mm footprint as the 168R1 series, 7.6 mm maximum height.
Stresses beyond values listed may cause permanent damage. Functional operation beyond any rating is not implied. All values at T<sub>amb</sub> = 25 °C unless noted.
