Author: Tanssion Date: 2023-05-03 Hits: 214

The part number UC3833DW is used to refer to a specific semiconductor device manufactured by Texas Instruments. The naming convention used for this part number is as follows:

UC3833DW

UC: This prefix is used to indicate that the part is a member of the UC family of devices, which are high-speed, high-performance power supply controllers.


3833: This number sequence indicates the specific model within the UC family. The first two digits, 38, represent the maximum voltage rating of the device (38 volts). The last two digits, 33, indicate that this device has two outputs and is capable of synchronous rectification.


DW: This suffix is used to indicate the package type of the device. In this case, DW refers to a 16-pin SOIC package with a surface-mount design.


The UC3833DW is a high-speed PWM controller designed for use in high-power and high-frequency applications. Some of the key parameters of this product include:


Input voltage range: 4.5V to 16.5V

Output voltage range: 0V to VCC

Maximum switching frequency: 1 MHz
