The LTC3814EFE-5#PBF is a synchronous step-up Switching Regulator Controller can generate output voltages up to 60V. The LTC3814-5 uses 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 1R 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.
