What are the key features of UCC1801J?
- Current-mode PWM control with programmable oscillator up to 500 kHz for tight loop regulation in isolated and non-isolated DC-DC converters
- Ultra-low 100 µA typical starting supply current minimizes power loss during startup in battery-powered and low-standby-power applications
- Integrated cycle-by-cycle current limiting, soft-start, and under-voltage lockout (UVLO) with 8.2 V turn-on threshold for robust protection
What is UCC1801J used for?
UCC1801J is used in offline flyback and forward converters, DC-DC modules, and power-supply units requiring current-mode PWM control with precise regulation from an 8.2 V to 12 V bias rail. Its 8-pin DIP form factor and integrated protection simplify board layout for industrial power supplies, telecom equipment, and battery chargers operating at switching frequencies up to 500 kHz.

Frequently Asked Questions
Which design situations make UCC1801J a practical choice from Texas Instruments?
UCC1801J is useful when the BOM needs a Integrated Circuit matching the approved electrical design, control, sensing, or power-management requirement. The available part context includes 8-pin, giving engineers a concrete parameter for datasheet and substitution checks.
How should layout teams check UCC1801J before approving an alternate?
For layout review, compare the approved Dual-In-Line Packages footprint, assembly method, and manufacturer documentation before substituting. Keeping 8-pin visible helps avoid alternates that change ratings, package fit, or qualification evidence.
What RFQ details help buyers source UCC1801J without creating a mismatch?
For RFQs, quote the exact UCC1801J, Texas Instruments manufacturer name, lifecycle expectations, and traceability needs. Supplier responses should preserve 8-pin or clearly explain any proposed alternate before purchase approval.
