BiCMOS Low-Power Current Mode PWM Controller

UCC38C4x family is a high-performance current-mode PWM Controller It is an enhanced BiCMOS version with pin-for-pin compatibility to the industry standard UC384xA family and UC384x family of PWM Controllers In addition, lower startup voltage ver 1283 sions of 7 V are offered as UCC38C40 and UCC38C41.
Providing necessary features to control fixed frequency, peak current-mode power supplies, this family offers the following performance advantages. The device offers 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 device also features a very 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 UCC38C4x family is offered in 8-pin packages, MSOP (DGK), SOIC (D) and PDIP (P).
