Description

LT3690EUFE#PBF Description
The LT3690EUFE#PBF is an adjustable frequency monolithic buck switching regulator that accepts input voltages up to 36V. A high-efficiency 90mΩ switch is included on the device along with the boost diode and the necessary oscillator, control, and logic circuitry. The internal synchronous power switch of 30mΩ increases efficiency and eliminates the need for an external Schottky catch diode.

LT3690EUFE#PBF Features
Wide Input Range: - Operation from 3.9V to 36V - Overvoltage Lockout Protects Circuits Through 60V Transients 4A Maximum Output Current Integrated 30mΩ N-Channel Synchronous Switch Programmable Input Undervoltage Lockout 0.8V Feedback Reference Voltage Output Voltage: 0.8V to 20V Programmable and Synchronizable Oscillator (170kHz to 1.5MHz) Soft-Startup and Output Voltage Tracking Short-Circuit Robust Power Good Flag Small Thermally Enhanced 4mm × 6mm QFN Package

LT3690EUFE#PBF Applications
Automotive Systems Industrial Supplies Distributed Supply Regulation
