LTC2927

Introduction

Multiple-voltage electronics systems often require complex supply voltage tracking or sequencing, which if not met, can result in system faults or even permanent failures in the field. The design difficulties in meeting these requirements are often compounded in distributed-power architectures where point-of-load (POL) DC/DC converters or linear regulators are scattered across PC board space, sometimes on different ...
