FEATURES
s s s s DESCRIPTIO s s s s s Wide Input Range: 7.4V to 40V Tolerates Input Transients to 60V 700mA Peak Switch Rating Adaptive Switch Drive Maintains Efficiency at High Load Without Pulse Skipping at Light Load True Current Mode Control 200kHz Fixed Operating Frequency Synchronizable to 400kHz Low Supply Current in Shutdown: 30µA Available in 8-Pin SO and PDIP Packages The LT®1776 is a wide input range, high efficiency Buck (step-down) switching regulator. The monolithic die includes all oscillator, control and protection circuitry. The part can accept input voltages as high as 60V and contains an output switch rated at 700mA peak current. Current mode control delivers excellent dynamic input supply rejection and short-circuit protection. At medium to high loads, the output switch circuitry maintains fast rise time for good efficiency. At light loads, rise time is deliberately reduced to avoid pulse skipping behavior. The available SO-8 package and 200kHz switching frequency allow for minimal PC board area requirements. , LTC and LT are registered trademarks of Linear Technology Corporation.
