LTC3541-2 Overview
The LTC®3541-2 bines a synchronous buck DC/ DC converter with a very low dropout linear regulator (VLDOTMregulator) and internal feedback resistor networks to provide two output voltages from a single input voltage with minimal external ponents. When configured for dual output operation, the LTC3541-2’s auto start-up feature will bring the 1.875V buck output into regulation in a controlled manner, prior to enabling the 1.5V VLDO output without the need for external pin control. The 1.5V VLDO/linear regulator output prior to 1.875V buck output sequencing may also be obtained via external pin control. The input voltage range is ideally suited for Li-Ion battery
