Product details

Automotive-grade PWM controller for isolated and non-isolated topologies

The Texas Instruments UCC2801QDRQ1 is a current-mode PWM controller qualified to AEC-Q100 for automotive applications. It supports boost, flyback, and forward converter topologies from a single 7.4 V to 12 V supply rail.

No clock sync — single-channel only

The UCC2801QDRQ1 does not support clock synchronization. That means you cannot phase-interleave multiple controllers to reduce input ripple or share thermal load. If your power stage needs more than one phase, this part is a single-phase solution. The single output drives one external power switch, and the control loop is compensated internally around the 46 kHz fixed frequency.

Active and available to quote

Per the manufacturer's status, the UCC2801QDRQ1 is currently active and in production. It is ROHS3 compliant and ships in Tape & Reel or Cut Tape from the 8-SOIC package.

Frequently asked questions

What is the maximum switching frequency of UCC2801QDRQ1?

The switching frequency is fixed at 46 kHz. There is no external frequency adjustment or synchronization pin.

Does UCC2801QDRQ1 support clock synchronization?

No. The UCC2801QDRQ1 does not have a clock synchronization feature. It operates as a standalone single-phase controller.

What is the equivalent part for UCC2801QDRQ1?

The UCC2806DWTR is a functional peer with a dual-output configuration, 50% duty cycle, and synchronous rectifier support, but it operates at 47 kHz and has an 8 V supply. The LM5150QURUMRQ1 is a higher-frequency (2.3 MHz) automotive boost controller with clock sync. Neither is a direct pin-for-pin replacement; verify compatibility with your layout and control requirements.
