Features & Applications

The IR3622 IC is a dual channel synchronous buck controller, providing a cost-effective, high performance and flexible solution. The two channels can be configured to either two independent outputs or current sharing single output. The current share configuration is ideal for high current applications.Key features offered by the IR3622 Include configurable dual output, output voltage tracking

Board Features:

  • The board is designed for two output voltages 2.5 V and 1.8 V up to 20 A for each output.
  • VIN= +12 V, (13.2 V Max).
  • VO1 = +2.5 V ±3% @ 20 A, VO2= +1.8 V± 3% @ 20 A.
  • Vo(ripple)= 50 mV maximum for each output.
  • Fs=350 kHz.
  • L1=990 nH, L2=540 nH.
  • Co1=2x100 uF (SP) + 2x10 uF (ceramic 0805) for 2.5 V output.
  • Co2=2x220 uF (SP) + 2x10 uF (ceramic 0805) for 1.8 V output.
  • The input voltage start threshold of the converter is set about 10 V using enable pin and two external resistors (R16A1 and R16A2).
  • The converter has the option to sequence with other supplies using SEQ and Track pins (R6A1, R16A3 and R16A4). These pins are pulled high as default.

Features:

  • Dual Synchronous Controller with 180o Out of Phase Operation.
  • Configurable to 2-Independent Outputs or Current Shared Single Output.
  • Output Voltage Tracking.
  • Power up / down Sequencing.
  • Current Sharing Using Inductor’s DCR.
  • +/-1% Accurate Reference Voltage.
  • Programmable Switching Frequency up 600 kHz.
  • Programmable Over Current Protection.
  • Hiccup Current Limit Using MOSFET Rds(on) sensing.
  • Latched Overvoltage Protection.
  • Dual Programmable Soft-Starts.
  • Programmable Enable Input.
  • Pre-Bias Start-up.
  • Dual Power Good Outputs.
  • On Board Regulator.
  • External Frequency Synchronization.
  • Thermal Protection.
  • 32-Lead MLPQ Package.
