UCC3585 - Low Voltage Synchronous Buck Controller

Download the UCC3585 datasheet PDF. This datasheet also covers the UCC2585 variant, as both devices belong to the same low voltage synchronous buck controller family and are provided as variant models within a single manufacturer datasheet.

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.

Key Features

  • D VOUT Resistor Programmable Down to 0.9 V D 3.3-V or 5.0-V Input Supply D 1% DC Accuracy D High Efficiency Synchronous Switching D Drives P-Channel (High Side) and N-Channel (Low Side) MOSFETs D Lossless Programmable Current Limit D Logic Compatible Shutdown.
