UCC28C40DR Description

Short technical summary and product information.

The UCC28C40DR from Texas Instruments is a low-power, current-mode Pulse Width Modulation (PWM) controller. It is suitable for various power supply topologies including Boost, Flyback, and Forward converters. This controller operates within a supply voltage range of 6.6V to 18V and supports a maximum duty cycle of 96% or 100% depending on the configuration.

 

Key electrical features include an adjustable switching frequency up to 1MHz, fast cycle-by-cycle overcurrent limiting with a 35ns response time, and a peak driving current of ±1A. It also incorporates undervoltage lockout (UVLO) protection at 7V/6.6V and a low operating current of 2.3mA. The device includes a precise 2.5V error amplifier reference with ±1% accuracy.

 

Packaged in an 8-SOIC (0.154", 3.90mm Width) surface-mount package, the UCC28C40DR is designed for efficient power management applications. Its operating temperature range is -40°C to 105°C (TJ). This controller is an enhanced replacement for older UCx84x and UCx84xA family devices, offering improved performance and functionality.
