i7C2W 20A DC-DC Converters

TDK Corporation has introduced the 20A 300W rated models to the TDK Lambda brand i7C series of non-isolated DC-DC converters with 8 to 24V adjustable output voltage. The new step-up and step-down converters are optimized to operate from a wide input voltage of 9 to 36V. The converters seamlessly transition from buck to boost mode operation without disruption in performance.

With the ability to deliver additional high power outputs from 12V or 24Vdc power supplies or batteries, the i7C2W 20A models have lower cost, smaller size, and high-efficiency levels of up to 97%. Along with reduced power consumption during light load conditions, the device draws typically just 5mA at zero loads, it can be reduced to around 0.25mA when the remote on-off puts the converter on standby.

With the package measuring 36.8mm in width, 34mm in length, and has a height of 14.7mm, these compact products are ideal for medical, industrial, automated guided vehicles, drones, and portable battery-powered equipment. The low quiescent current allows battery-powered equipment to remain functional longer during periods of non-operation.

Features of i7C2W 20A DC-DC Converters

  • Up to 300W in a 1/16th Brick Pin-Out
  • High Efficiency - Up to 97%
  • Wide 5 to 28V, 8 to 24V, or 9.6 to 48V Output Adjustment
  • Wide 9 to 36V or 9 to 53Vdc Input Range
  • Low Component Count With Minimal External Components
  • Low Airflow With Minimal Derating Requirements

The i7C2W series features include a trim pin for output voltage adjustment, + remote sense, remote on-off (positive or negative logic), input under-voltage, over-current, and over-temperature protection. All models have safety certification to the IEC/UL/CSA/EN 62368-1 standard, with CE marking to the Low Voltage and RoHS Directives.
