LTM4691EY#PBF

LTM4691 is a high efficiency, dual, step-down DC/DC module regulator. This device operates in forced continuous mode for low noise pulse-skipping mode or Burst Mode operation for high efficiency at lights loads. The typical buck switching frequency is 2MHz and can be synchronized from 1MHz to 3MHz. Its high switching frequency and a current mode architecture enables a very fast transient response to line and load changes without sacrificing stability. Other features include precision run thresholds, a PGOOD signal, output overvoltage protection, thermal shutdown and output short-circuit protection. This device is Pb-free and RoHS compliant. It is widely used in application such as telecom, networking and industrial equipment, point-of-load regulation, FPGA, ASIC core supplies etc.
