LTC3541-3 Overview
Description
The LTC®3541-3 combines a synchronous buck DC/DC converter with a very low dropout linear regulator (VLDO™ regulator) and internal feedback resistor networks to provide two output voltages from a single input voltage with minimum external components. When configured for dual output operation, the LTC3541-3’s auto start-up feature will bring the 1.575V VLDO/linear regulator output into regulation in a controlled manner prior to enabling the 1.8V buck output without the need for external pin control.
