The UCC38C43D from Texas Instruments is a high-performance, current-mode Pulse Width Modulation (PWM) controller. It is an enhanced BiCMOS version offering pin-for-pin compatibility with the industry-standard UCx84xA and UCx84x families. This controller operates with a voltage range of 7.6V to 18V and supports topologies such as Boost, Flyback, and Forward Converter.
Key electrical features include an operating frequency of up to 1MHz, a maximum startup current of 50µA, and a low operating current of 2.3mA. It provides fast, cycle-by-cycle overcurrent limiting in 35ns, with peak driving current capability of ±1A. The device also features a ±1% accurate 2.5V error amplifier reference and undervoltage lockout protections at 8.4V/7.6V.
Packaged in an 8-SOIC (0.154", 3.90mm Width) surface-mount package, the UCC38C43D is suitable for space-constrained designs. Its operating temperature range is 0°C to 85°C. This part is noted as being obsolete and no longer in production.
