Technical Details & Description

PWM controller for boost, flyback, and forward converters

The Texas Instruments UCC2806DWTR is a current-mode PWM controller that handles step-up and step-up/step-down topologies—boost, flyback, and forward converter—from a single 8 V to 14.5 V supply rail. It drives two transistor outputs at a fixed 47 kHz switching frequency, with a maximum duty cycle of 50%. The controller includes current limit, enable, and frequency control, plus a synchronous rectifier driver.

The 47 kHz switching frequency and 50% duty-cycle cap are fixed limits. The duty-cycle cap ensures the transformer resets fully each cycle in a flyback.

There is no last-time-buy or end-of-life notice.

Frequently asked questions

Where can I buy UCC2806DWTR and how do I get a price?

UCC2806DWTR is sourced to order through independent distribution. Submit an RFQ for current availability and pricing—quotes are confirmed at request time.

What is the pinout of UCC2806DWTR?

The pinout is defined by the 16-SOIC package (0.295" body width, 7.50 mm pitch). Refer to the Texas Instruments datasheet for the full pin assignment and functional description.

What is UCC2806DWTR's listed function?

The UCC2806DWTR is a current-mode PWM controller supporting step-up and step-up/step-down topologies: boost, flyback, and forward converter.

What is the cross-reference or equivalent replacement for UCC2806DWTR?

For a higher-frequency, automotive-grade alternative, consider the LM5150QURUMRQ1 (boost only, single output, up to 2.3 MHz, AEC-Q100). For a dual-output flyback/forward controller at low frequency, the UCC2806 remains the direct choice.
