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

Texas Instruments UC2846DW is a 16-pin SOIC packaged 2-channel current mode PWM controller designed for power management IC applications requiring switching frequencies up to 500 kHz and a maximum supply voltage of 125 volts. It features surface mount construction suitable for compact PCB layouts.

This device supports flyback power supply topology with current control enabling precise constant-voltage (CV) and constant-current (CC) output regulation. Its primary-side regulation (PSR) capability eliminates the need for an optocoupler, which enhances transient response for large load steps.

The UC2846DW has a low supply current of 4 mA, output voltage rating of 5.2 volts, and output current up to 500 mA, providing efficient operation in power control circuits. With a maximum duty cycle of 50%, it ensures controlled power delivery and protects against overdriving.

Designed to operate within an ambient temperature range from -40 to 85 degrees Celsius, this controller is reliable across typical industrial application environments. Its compact physical dimensions of 2.35 mm height, 10.28 mm length, and 7.52 mm width fit compact power supply designs.

This PWM controller is ideal for industrial, automation, and power supply management applications where efficient, stable, and discrete PWM outputs are essential. It belongs to the UC series of controllers by Texas Instruments which are widely recognized for their quality and performance.

Designed for surface mount with 16-pin SOIC package. Current-mode control for precise PWM regulation. Supports switching frequencies up to 500 kHz. Two PWM output channels available. Wide operating temperature range from -40°C to 85°C.

Eliminates optocoupler by primary-side regulation. Low supply current of 4 mA for power efficiency. Compact footprint suitable for dense PCB layouts.
