UC3846DWTR Description

Short technical summary and product information.

The UC3846DWTR from Texas Instruments is a versatile current mode PWM controller. It is designed to implement fixed-frequency, current-mode control schemes with a minimal external component count. This controller features automatic feedforward compensation and programmable pulse-by-pulse current limiting, enhancing line regulation and load response characteristics.

 

Key electrical specifications include an operating voltage range of 6.95V to 40V and a maximum operating frequency of 500kHz. It supports a maximum duty cycle of 50% and offers features such as soft start, undervoltage lockout, and a shutdown terminal. The device also includes a ±1% band gap reference and 500mA totem-pole outputs.

 

Packaged in a 16-SOIC (0.295", 7.50mm Width) surface mount package, the UC3846DWTR is suitable for various power converter applications. Its operating temperature range is 0°C to 70°C (TA). The controller's capabilities extend to parallel operation for modular power systems and a differential current sense amplifier with a wide common-mode range.
