LT3430IFE#TRPBF

LT3430 is a monolithic buck switching regulator. A current mode architecture provides fast transient response and excellent loop stability. Special design techniques and a new high voltage process achieve high efficiency over a wide input range. Efficiency is maintained over a wide output current range by using the output to bias the circuitry and by utilizing a supply boost capacitor to saturate the power switch. Patented circuitry maintains peak switch current over the full duty cycle range. It is widely used in application such as industrial and automotive power supplies, portable computers, battery chargers, distributed power systems etc.
