Description
General part information
LT8350S Series
The LT8350S is a monolithic 4-switch synchronous buck-boost converter with second-generation Silent Switcher architecture to minimize electromagnetic interference (EMI) emissions while delivering high efficiency at high switching frequency. The switcher can regulate the output voltage, input or output current from input voltages above, below, or equal to the output voltage. The proprietary peak current mode control scheme allows for the synchronization and adjustment of 200kHz to 2MHz fixed frequency operation or spread spectrum frequency modulation (SSFM) operation. With a 3V to 40V input voltage range, 1V to 18V output voltage capability, and seamless low noise transitions between operation regions, the LT8350S is ideal for voltage regulator, battery, and super-capacitor charger applications in automotive, industrial, telecom, and battery-powered systems.The LT8350S provide an input or output current monitor and power good flag. Robust fault protection is provided to detect output short-circuit conditions, during which the LT8350S retries, latches off, or keeps running.ApplicationsAutomotive, Industrial, Telecom SystemsVoltage Regulator with Accurate Current LimitHigh-Frequency Battery-Powered SystemUSB Power Delivery (USB-PD) Source
