UCC3585M Description

Short technical summary and product information.

The UCC3585M from Texas Instruments is a high-efficiency synchronous buck controller. It is designed to provide flexible power conversion for low voltage systems, supporting an input voltage range of 3.0V to 5.5V. The controller is capable of delivering output voltages down to 0.9V with a guaranteed ±1% DC accuracy.

 

Featuring a fixed-frequency oscillator, the UCC3585M supports PWM operation up to 500 kHz. It drives complementary P-channel (high-side) and N-channel (low-side) MOSFETs for efficient step-down voltage conversion. The device includes control features such as current limit, enable, frequency control, and soft start, enhancing application flexibility.

 

This controller is housed in a 16-SSOP package and is designed for surface mount applications. Its operating temperature range is 0°C to 85°C (TA). The UCC3585M is suitable for applications requiring precise voltage regulation and high efficiency, such as microprocessor core voltage supplies.
