28V, 5A Low IQSynchronous Step-Up Silent Switcher with PassThru

Description

The LT8337/LT8337-1 is a low IQ, synchronous step-up DC/DC converter. It features Silent Switcher architecture and optional spread spectrum frequency modulation (SSFM) to minimize EMI emissions while delivering high efficiencies at high switching frequencies.The wide input/output voltage range, low VINpin quiescent current in Burst Mode operation, and 100% duty-cycle capability for the synchronous MOSFET in PassThru operation (VIN> VOUT) makes the LT8337/LT8337-1 ideally suited for battery-powered systems and general purpose step-up applications.The LT8337/LT8337-1 integrates 28V, 5A power switches, operating at a fixed switching frequency programmable between 300kHz and 3MHz and synchronizable to an external clock. The LT8337/LT8337-1 features output soft-start and output overvoltage lockout.The LT8337-1 allows external compensation via the VCpin for fast transient response. The LT8337 offers an output power good flag via the PG pin.ApplicationsBattery-Powered SystemsGeneral Purpose Step-Up
