Description
General part information
LTC3814-5 Series
The LTC3814-5 is a synchronous step-up switching regulator controller that can generate output voltages up to 60V. The LTC3814-5 uses a constant off-time peak current control architecture to deliver very high duty cycles with accurate cycle-by-cycle current limit without requiring a sense resistor.A precise internal reference provides ±0.5% DC accuracy. A high bandwidth (25MHz) error amplifier provides very fast line and load transient response. Large 1Ω gate drivers allow the LTC3814-5 to drive large power MOSFETs for higher current applications. The operating frequency is selected by an external resistor and is compensated for variations in VIN. A shutdown pin allows the LTC3814-5 to be turned off reducing the supply current to <230μA.Applications24V Fan Supplies48V Telecom and Base Station Power SuppliesNetworking Equipment, ServersAutomotive and Industrial Control Systems
