LT3514EFE#PBF Datasheet PDF - Linear Technology

●The LT3514EFE#PBF is a Triple Step-down Switching Regulator with 100% duty cycle operation. It has a wide operating input range of 3.2 to 36V. An on-chip boost regulator allows each channel to operate up to 100% duty cycle. The LT3514 is designed to minimize external component count and results in a simple and small application circuit. It operates robustly in fault conditions. Cycle-by-cycle peak current limit and catch diode current limit sensing protect the IC during overload conditions. Thermal shutdown protects the power switches at elevated temperatures. Soft-start helps control the peak inductor current 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.
