The LT8336 is a low IQ, synchronous step-up DC/DC converter. It features Silent Switcher architecture and optional spread spectrum frequency modulation to minimize EMI emissions while delivering high efficiencies at high switching frequencies.
The wide input/output voltage range, low VIN pin quiescent current in Burst Mode operation, and 100% duty cycle capability for the synchronous MOSFET in PassThru operation (VIN ≥ VOUT), make the LT8336 ideally suited for general purpose step-up and automotive preboost applications.
The LT8336 integrates 40V, 2.5A power switches, operating at a fixed switching frequency programmable between 300kHz and 3MHz and synchronizable to an external clock. Pulse-skipping or Burst Mode operation can be selected, with or without spread-spectrum frequency modulation, to optimize efficiency and EMI performance.
The LT8336 features output soft-start, an output power good flag and output overvoltage lockout.
