Description
General part information
LT1776 Series
The LT1776 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.The LT1776 contains several features to enhance efficiency. The internal control circuitry is normally powered via the VCCpin, thereby minimizing power drawn directly from the VINsupply. The action of the LT1776 switch circuitry is also load dependent. 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.ApplicationsAutomotive DC/DC ConvertersCellular Phone Battery Charger AccessoriesIEEE 1394 Step-Down Converters
