The UCC28C4x-Q1 family devices are high performance current-mode PWM controllers. They
are enhanced BiCMOS versions with pin-for-pin compatibility to the industry standard UC28C4x family
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.
The UCC28C4x-Q1 family is offered in the 8-pin SOIC (D) package.
