MAX8546EUB+T

Product Overview

The MAX8546EUB+T from Analog Devices Inc./Maxim Integrated is a positive-output step-down DC-DC controller with a single output phase and a transistor-driver output. It operates from a 2.7 V to 28 V supply and uses a 300 kHz switching frequency with a maximum 86% duty cycle. The device includes an enable control and synchronous rectifier support, and uses a surface-mount 10-uMAX/uSOP package.

Key Features

• Single positive buck output with one output phase
• Supply voltage range of 2.7 V to 28 V
• 300 kHz switching frequency
• Maximum duty cycle of 86%
• Synchronous rectifier support with transistor-driver output
• Enable control and surface-mount 10-uMAX/uSOP package
• Operating temperature range of -40°C to +85°C (TA)

Applications

• Point-of-load power conversion in compact electronic assemblies
• Systems requiring a positive step-down rail from a 2.7 V to 28 V input
• Enable-controlled activation of a single output rail

Design & Procurement Notes

Designers should verify that the selected circuit components and PCB layout are compatible with the transistor-driver output, 300 kHz switching frequency and 86% maximum duty cycle. The 2.7 V to 28 V supply range and -40°C to +85°C ambient operating range should be checked against the final board conditions. The enable function can be used for controlled activation, while the 10-uMAX/uSOP surface-mount package supports compact board placement.
