1 / 32 page LTC3813 1 3813fb 100V Current Mode Synchronous Step-Up Controller The LTC3813 is a synchronous step-up switching regulator controller that can generate output voltages up to 100V. The LTC3813 uses a constant off-time peak current control architecture 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 LTC3813 to drive multiple MOSFETs for higher current applications. The operating frequency is selected by an external resistor and is compensated for variations in VIN and can also be synchronized to an external clock for switching-noise sensitive applications. A shutdown pin allows the LTC3813 to be turned off, reducing the supply current to 240μA.
