Description

General part information

LT8292 Series

LT8292 is a synchronous 4-switch buck-boost controller that regulates output voltage and output or input current from an input voltage above, below, or equal to the output voltage. The proprietary buck-boost peak current mode architecture allows adjustable and phase-lockable 100kHz to 650kHz fixed frequency operation, or internal spread spectrum operation for low electromagnetic interference (EMI). When the output is regulated above 5V, the LT8292 can operate from an input supply as low as 3V after start-up.The low quiescent current at no-load extends operating run time in battery-powered systems. At light load, either forced continuous, pulse-skipping, or low-ripple Burst Mode can be selected.The LT8292 features split pull-up/pull-down gate drivers and four selectable dead time settings with shootthrough protection, which allows both optimized efficiency and EMI. Fault protection is also provided to detect output short-circuit conditions, during which the LT8292 runs in low-duty cycle auto-retry mode.APPLICATIONSAutomotive, Industrial, Telecom SystemsGeneral Purpose Buck-Boost Power SuppliesHigh-Power Battery-Powered Systems
