Digitally controlled small-footprint PoL converter modules up to 18A
The added models accept input voltages from 4.5V to 14V and have an adjustable output voltage range from 0.6V to 5V (1.8V max for 18A model). Designed for a minimal footprint, the high-power-density LGA modules measure 12.2 x 12.2 x 8.0 mm (0.48 x 0.48 x 0.315 in). The converters offer a typical efficiency figure of 91.6% at 12 Vin, and are able to operate in a temperature range of -30 to +95C. All power management functions can be reconfigured for user-specific needs using the PMBus interface.
Included as standard features are short circuit, over current, over voltage, over temperature, and input under voltage protection, voltage margining and tracking, power-good, remote sense, and remote on/off. The converters employ adaptive compensation of the PWM control loop, a phase spreading feature to reduce input capacitance, synchronisation to reduce EMI filtering, and an optimised dead time control. The OKDL converters are delivered with a default firmware configuration suitable for a wide range of input voltage, output voltage, and load.
The OKDL products comply with the “picoAMP” standard from the Architects of Modern Power (AMP) group of companies, which guarantees customers multiple sources of interoperable products.
