Product Overview
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.
- Input voltage range is 2.25V to 3.6V
- Dual 2A DC output current
- Total output voltage regulation is ±1.5%
- Current mode control, fast transient response
- External frequency synchronization
- 180° out-of-phase operation
- Power good indicator, internal soft-start
- Selectable pulse-skipping mode/Burst Mode® operation/forced continuous mode
- Operating temperature is -40°C to 125°C
- Package style is 24-lead LGA
