The 48% maximum duty cycle ensures transformer reset in single-ended forward converters. Switching frequency runs up to 500 kHz. Output is a single transistor driver with positive, isolation-capable configuration. Operating temperature spans -40°C to 85°C ambient. ## RoHS compliance — critical for EU and green-markets This part is marked RoHS non-compliant. That means it contains lead (Pb) in the solder finish or die attach, and cannot be used in products sold into EU RoHS jurisdictions without an exemption. For military, aerospace, or industrial applications with a RoHS waiver, the non-compliant status is acceptable and may even be preferred for reliability in high-temperature or high-vibration environments. ## Package and handling Housed in an 8-pin PDIP (0.300\" width, 7.62 mm body) with through-hole mounting. The package is listed as Bulk.","metaTitle":"UC2845P PWM Controller, 48% Duty Cycle, 500kHz, 8-PDIP","metaDescription":"UC2845P current-mode PWM controller.
