(1) Component qualification in accordance with JEDEC and

industry standards to ensure reliable operation over an

extended temperature range. This includes, but is not limited

to, Highly Accelerated Stress Test (HAST) or biased 85/85,

temperature cycle, autoclave or unbiased HAST,

electromigration, bond intermetallic life, and mold compound

life. Such qualification testing should not be viewed as

justifying use of this component beyond specified

performance and environmental limits.

DESCRIPTION

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, lower startup voltage versions of 7 V are offered as UCC28C40 and 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.

The UCC28C4x family is offered in 8-pin package SOIC (D).

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas

Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
