Control features include current limit, frequency control, a programmable ramp, and soft start. The 100% max duty cycle allows the low-side switch to stay on through the full period in boost or flyback, simplifying the transformer reset design. ## Package and temperature grade Housed in a 16-pin PDIP (0.300\" body, 7.62 mm width), the through-hole package suits prototyping, low-volume builds, and boards where rework access matters — the pin pitch is 2.54 mm, compatible with standard perfboard and sockets. For extended-temperature designs (e.g., -40 °C to +85 °C), a different grade variant would be needed. Pricing and lead time confirmed at RFQ against the buyer's quantity and delivery window.","metaTitle":"Texas Instruments UC3823AN PWM Controller, 400kHz-1MHz","metaDescription":"Active-production UC3823AN PWM controller from Texas Instruments.
