LT1956EFE#PBF Datasheet PDF - Linear Technology

●The LT1956EFE#PBF is a monolithic buck Switching Regulator with an input voltage capability up to 60V. A high efficiency 1.5A, 0.2R 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 25µA and the device can be externally synchronized from 580 to 700kHz with a logic level input.
