The LT®3504 consists of four 1A output current buck regulators. An on-chip boost regulator allows each channel to operate up to 100% duty cycle and eliminates the need for four external charge pump circuits. The LT3504 operates robustly in fault conditions. Cycleby-cycle peak current limit and catch diode current limit sensing protect the part during overload conditions.
