Description

General part information

LT8604/LT8604C Series

The LT8604/LT8604C is a compact, high speed synchronous monolithic step-down switching regulator that delivers up to 120mA to the output with high efficiency at a constant frequency, even up to 2.2MHz. It accepts a wide input voltage range up to 42V and consumes only 2.5μA of quiescent current when operating in Burst Mode. Top and bottom power switches are included with all necessary circuitry to minimize the need for external components.The LT8604C includes BST and INTVCCceramic capacitors for a more compact solution while having SYNC/MODE and HYST pins. The SYNC/MODE pin selects the regulator’s operation between forced continuous mode, for predictive interference in sampling systems, Burst Mode, for increased efficiency at light loads or spread spectrum for Low EMI. It also allows synchronization to an external clock to further increase signal to noise ratio in high-resolution acquisition systems.A PG flag signals when VOUTis within ±7.5% of the programmed output voltage and when in fault conditions. Thermal shutdown provides additional protection.ApplicationsIndustrial SensorsIndustrial Internet of Things4mA to 20mA Current LoopsFlow MetersAutomotive Housekeeping Supplies
