The Texas Instruments UCC38C43P is a high-performance, current-mode 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 low startup current of 50µA maximum and a low operating current of 2.3mA at 52kHz.
Key electrical specifications include an operating voltage range of 7.6V to 18V and a maximum duty cycle of 100%. It features adjustable switching frequency up to 1MHz, fast cycle-by-cycle overcurrent limiting (35ns), and a ±1A peak driving current. The device includes a ±1% accurate 2.5V error amplifier reference and undervoltage lockout protections at 8.4V/7.6V.
The UCC38C43P supports multiple topologies including Boost, Buck, Flyback, and SEPIC. It is housed in an 8-PDIP package suitable for through-hole mounting. This controller is an enhanced replacement for older UCx84x series controllers, offering improved efficiency due to lower power consumption.
This component is well-suited for AC/DC and DC/DC power supply designs requiring precise current control and high efficiency. Its features make it a versatile choice for various power management applications.
