UCC3585 Datasheet Low Voltage Synchronous Buck Controller

Manufacturer: Texas Instruments

Overview: UCC3585 Not Recommended for New Designs UCC2585 UCC3585 SLUS304F − JULY 1999 − REVISED JANUARY 2005 LOWĆVOLTAGE SYNCHRONOUS BUCK.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The UCC3585 synchronous buck controller provides flexible high efficiency power conversion for output voltages as low as 0.9 V with ensured ±1% dc accuracy.

With an input voltage range of 3.0 V to 5.5 V, it is the ideal choice for 3.3 V only, 5.0 V only, or other low voltage systems.

The fixed frequency oscillator is capable of providing practical PWM operation to 500 kHz.
