LT3514IFE Products

The LT3514IFE#PBF consists of three buck regulators (2A, 1A, 1A output current). The device has a wide operating input range of 3.2V to 36V. An on-chip boost regulator allows each channel to operate up to 100% duty cycle. The LT3514IFE#PBF is designed to minimize external component count and results in a simple and small application circuit.

The LT3514IFE#PBF operates robustly in fault conditions. Cycleby- 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.

The LT3514IFE#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.

The LT3514IFE#PBF has one fewer channel (CH2) than the LT3504, and has one channel (CH3) that outputs 2A instead of 1A. The LT3514IFE#PBF in QFN is pin compatible with the LT3504. The LT3504 provides four 1A outputs.
