Description

General part information

LT8338 Series

The LT8338 is a synchronous monolithic step-up regulator that provides high efficiency for input and output up to 40V. It consumes only 6μA quiescent current at Burst Mode operation to maintain high efficiency at very low output current, while keeping the output ripple below 20mVP-P. The LT8338 switching frequency can be set with an external resistor over the range of 300kHz to 3MHz. A SYNC/MODE pin allows synchronization to an external clock. It can also be used to select between Burst Mode operation and pulse-skipping mode, or to enable spread spectrum modulation to reduce EMI. The EN/UVLO pin has an accurate 1V threshold and can be used to program VINUVLO or to shut down the part. The LT8338 enters 100% duty cycle PassThru mode when VINis higher than the regulated VOUT. The LT8338 also features frequency foldback and internal soft-start for inductor current control during start-up.APPLICATIONSIndustrial and Automotive Power SuppliesBattery-Powered SystemsGeneral Purpose Step-Up
