LT1956EFE ADI Integrated Circuits (ICs) - Jotrin Electronics

This is one LOT (Qty.5) of New Linear Technology High Voltage 1.5A 500KHz Step Down DC/DC Switching Regulator. Part Number: LT1956EFE in SSOP-16 Package. General Spec for LT1956EFE: Wide Input Range: 5.5V to 60V Peak Switching Current: 1.5A Constant Switching Frequency: 500KHz 16-Lead SSOP Package The LT1956/LT1956-5 are 500kHz monolithic buck switching regulators with an input voltage capability up to 60V. A high efficiency 1.5A, 0.2 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 25µA and the device can be externally synchronized from 580kHz to 700kHz with a logic level input. The LT1956/LT1956-5 are available in fused-lead 16-pin SSOP and thermally enhanced TSSOP packages. Spec see
