High accuracy step down DC/DC Controller from Linear Technology

Linear's new stepdown DC/DC Controller LTC3823 offers differential remote output voltage sensing of both positive and negative outputs. The input voltage range is 4.5 to 30 V. Deliver output voltage range of 0.6V to 90% of input voltage. It responds instantly to sudden load change due to constant on-time architecture. This device works on current mode control by sensing voltage drop across synchronous power MOSFET. The current limit can be programmable to optimize system efficiency and to get better control over the maximum output current.

The output voltage is accurate to +/-0.67% in the temperature range of 0 Deg to 85 Deg C. The LTC3823 can be configured for phase-lock loop frequency synchronization
