Its primary application is in off-line and DC-DC resonant converters where soft-switching reduces switching losses and EMI. ## Active lifecycle — no obsolescence concern For MRO planners stocking spares, this part does not present an imminent obsolescence risk — though given the age of the resonant-mode controller family, keeping a small buffer is prudent if the design is long-lived.","metaTitle":"UC2864DW/81167 Resonant Mode PWM Controller, Active, Bulk","metaDescription":"UC2864DW/81167 resonant mode power supply controller from Texas Instruments.
