UCC2806MTR

The Texas Instruments UCC2806MTR is a BiCMOS PWM controller from the UCC3806 family, offering improved performance and reduced bias current. It features a familiar architecture with the same block diagram and pinout as the UC3846 series, enabling higher switching frequencies.

Key electrical specifications include an operating voltage range of 8V to 14.5V, a maximum operating current of 1.4 mA, and a startup current of 100 μA. The device provides ±0.5 A peak output current and a circuit delay of 125 ns. It supports various topologies including Boost, Flyback, and Forward converters, with a duty cycle limit of 50% and a frequency of 47 kHz.

Designed for versatility, the UCC2806MTR offers dual high-current MOSFET driving outputs and a fast current sense loop. Control features include current limit, enable, and frequency control. The controller is suitable for applications ranging from off-line power supplies to battery-operated portable equipment.

This component is available in a 16-SSOP surface mount package, measuring 0.154" (3.90mm) in width. It operates within an ambient temperature range of -40°C to 85°C. The RoHS status is RoHS3 Compliant, and it has a Moisture Sensitivity Level (MSL) of 1.
