UCC28C41-Q1,UCC28C43-Q1,UCC28C

The UCC28C4x family are high performance current-mode PWM controllers. They are enhanced BiCMOS versions with pin-for-pin compatibility to the industry standard UC284xA family and UC284x family of PWM controllers. In addition, a lower startup voltage versions of 7 V is offered as UCC28C41.

Providing necessary features to control fixed frequency, peak current mode power supplies, this family offers several performance advantages. These devices offer high frequency operation up to 1 MHz with low start up and operating currents, thus minimizing start up loss and low operating power consumption for improved efficiency. The devices also feature a fast current sense to output delay time of 35 ns, and a ±1-A peak output current capability with improved rise and fall times for driving large external MOSFETs directly.
