Texas Instruments 16-Pin SOIC 2-Channel Current Mode PWM Controller 500 kHz 125V UC2846DW

Texas Instruments UC2846DW is a 16-Pin Surface Mount SOIC pack 2-Channel Current Mode PWM Controller designed for power management applications requiring switching frequencies up to 500 kHz and maximum supply voltages up to 125V. It supports both Constant-Voltage (CV) and Constant-Current (CC) output regulation, providing improved transient response during large load steps, ideal for flyback converter designs.

The device features a low supply current of 4mA and provides 5.2V output voltage with a maximum output current of 500mA. Its thermal operating range from -40°C to 85°C makes it suitable for a variety of industrial environments.

Packaged in a compact 16-pin SOIC with dimensions 10.28mm length, 7.52mm width, and 2.35mm height, it allows easy surface mounting on PCBs for efficient assembly. The controller employs Primary-Side Regulation (PSR), eliminating the need for an optocoupler and simplifying isolation in flyback power supplies.

With a maximum duty cycle of 50%, it ensures effective switching and current control, enabling steady output regulation. The UC2846DW belongs to the UC series of controllers from Texas Instruments targeted at power conversion and motor control circuits.

Features a current mode PWM controller type with two outputs for efficient power management. Offers a supply current of 4mA and an output current of 500mA at 5.2V output voltage. Supports wide operating temperature range from -40°C to 85°C ensuring reliable performance.

Designed with a Surface Mount package type SOIC with 16 pins measuring 10.28mm length, 7.52mm width, and 2.35mm height. Incorporates Primary-Side Regulation (PSR) for flyback power supply applications enhancing transient response.
