Analog Devices Inc. LT8336 Step-Up Silent Switcher® DC-DC Converter uses a fixed frequency, current mode control scheme to provide excellent line and load regulation. This low IQ, synchronous DC-DC converter uses 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 pass-through operation (VIN ≥ VOUT), make the LT8336 ideally suited for general purpose step-up and automotive pre-boost 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. This device also features output soft-start, an output Power Good flag, and output overvoltage lockout.
The Analog Devices Inc. LT8336 DC-DC Converter is available in a compact QFN16 package, and is offered with both a standard -40°C to +125°C and extended -40°C to +150°C operating temperature range.
