A high efficiency 3A, 0.1 Ohm switch is included on the die along with all the necessary oscillator, control and logic circuitry. A current mode architecture provides fast transient response and good 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. A shutdown pin reduces supply current to 30μA and the device can be externally synchronized from 580kHz to 700kHz with logic level inputs.The LT3431 is available in a thermally enhanced 16-pin TSSOP package.
