Product Information
Product Overview
LT8338 is a synchronous monolithic step-up regulator that provides high efficiency for input and output upto 40V. This device 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 VIN UVLO or to shut down the part. This device enters 100% duty cycle Pass Thru mode when VIN is higher than the regulated VOUT. It also features frequency foldback and internal soft-start for inductor current control during start-up. It is widely used in application such as industrial and automotive power supplies, battery-powered systems, general purpose step-up.
