Description

General part information

LT8334 Series

The LT8334 is a current mode DC/DC converter with a 40V, 5A switch operating from a 2.8V to 40V input. With a unique single feedback pin architecture, it is capable of boost, SEPIC or inverting configurations. Burst Mode operation consumes as low as 9μA quiescent current to maintain high efficiency at very low output currents, while keeping typical output ripple below 15mV.An external compensation pin allows optimization of loop bandwidth over a wide range of input and output voltages and programmable switching frequencies between 300kHz and 2MHz. A SYNC/MODE pin allows synchronization to an external clock. It can also be used to select between BURST or PULSE SKIP modes of operation with spread spectrum frequency modulation for low EMI. For increased efficiency, a BIAS pin can accept a second input to supply the INTVCCregulator. Additional features include frequency foldback and programmable soft-start to control inductor current during start-up.The LT8334 is available in a thermally enhanced 12-lead 4mm × 3mm DFN package.APPLICATIONSIndustrial and AutomotiveTelecomMedical Diagnostic EquipmentPortable Electronics
