TEXAS INSTRUMENTS UCC28C43DGK 控制器, 电流模式控制器, PWM, 20V-7.6V电源, 1 MHz, 18V/1A输出, MSOP-8
The is a low-power BiCMOS current-mode Pulse Width Modulation PWM Controller with pin-for-pin compatibility to the industry standard UC384xA family and UC384x family of PWM controllers. It provides necessary features to control fixed frequency and peak current-mode power supplies. The device offers high-frequency operation up to 1MHz with low start-up and operating currents, thus minimizing start-up loss and low operating power consumption for improved efficiency. It features a very fast current-sense-to-output delay time of 35ns and a ±1A peak output current capability with improved rise and fall times for driving large external MOSFETs directly.
