Product Overview

The LT3504EUFD#PBF is a quad step-down Switching Regulator with 100% duty cycle operation. 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. It is designed to minimize external component count and results in a simple and small application circuit. The LT3504 operates robustly in fault conditions. Cycle-by-cycle peak current limit and catch diode current limit sensing protect the part during overload conditions. Thermal shutdown protects the power switches at elevated temperatures. Soft-start helps keep the peak inductor current under control during startup. It also features output voltage tracking and sequencing, programmable frequency, programmable undervoltage lockout and a power good pin to indicate when all outputs are in regulation.
