CH13 series wide-input offline bias flyback transformers supply the housekeeping rails for off-line converters — a 12 V primary-side auxiliary winding plus a 10 V secondary output — from a 60–400 Vin range. Flip mode CCM, BCM or DCM by choosing Lp, so the same part number suits either efficiency-led or cost-led bias designs. Proven in offline DC-DC reference designs such as the LT3752-1 / LT8311 based DC1929A.
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.
