Introduction
The UC3846DWTR is a high-performance current-mode PWM controller chip designed for use in various power supply applications, including AC/DC and DC/DC converters. This chip features an operating frequency range of up to 500kHz and can provide precise control of the output voltage and current. It includes a built-in error amplifier, a current-sense amplifier, a voltage reference, and a high-speed output driver. Other features include soft-start, shutdown, and overcurrent protection. The UC3846DWTR is available in a small, space-saving 16-pin TSSOP package, making it suitable for use in compact power supply designs.
Application
The UC3846DWTR is a versatile PWM controller IC that finds extensive use in various power supply applications, including AC/DC and DC/DC converters, battery chargers, LED drivers, and motor control systems. In the industrial sector, it is commonly used for high-power applications such as welding machines, switch-mode power supplies (SMPS), and uninterruptible power supplies (UPS). In the automotive industry, it is used for electric vehicle (EV) powertrain systems and battery management systems (BMS). The UC3846DWTR's high-frequency operation and precise control of the output voltage and current make it an ideal choice for applications that require high efficiency and fast transient response. Its small package size and robust design make it suitable for harsh environments and space-constrained applications.
