MAX5066 - Synchronous Buck Controller

General Description

The MAX5066 is a two-phase, configurable single- or dual-output buck controller with an input voltage range of 4.75V to 5.5V or from 5V to 28V.

Each phase of the MAX5066 is designed for 180° operation.

Key Features

  • include thermal shutdown, “hiccup mode” short-circuit protection. Use the MAX5066 with adaptive voltage positioning for.

19-3661; Rev 1; 8/05 KIT ATION EVALU LE B A IL A AV Configurable, Single-/Dual-Output, Synchronous Buck Controller for High-Current Applications General Description The MAX5066 is a two-phase, configurable single- or dual-output buck controller with an input voltage range of 4.75V to 5.5V or from 5V to 28V. Each phase of the MAX5066 is designed for 180° operation. A mode pin allows for a dual-output supply or connecting two phases together for a single-output, high-current supply. Each output channel of the MAX5066 drives n-channel MOSFETs and is capable of providing more than 25A of load current. The MAX5066 uses average current-mode control with a switching frequency up to 1MHz per phase where each phase is 180° out of phase with respect to the other.
