LT3504EUFD#PBF 製品詳細

The LT3504EUFD#PBF consists of four 1A output current buck regulators. The LT3504EUFD#PBF has a wide operating input range of 3.2V to 40V. 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 LT3504EUFD#PBF is designed to minimize external component count and results in a simple and small application circuit.

The LT3504EUFD#PBF 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.

The LT3504EUFD#PBF 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.
