Digitally-controlled PoL converters are in high density packaging
The Okami series of non-isolated PoL DC/DC converters is made up of the OKDL-T/6-W12, OKDL-T/12-W12, and OKDL-T/18-W12, delivering 6, 12, and 18A respectively. They can be monitored and configured via PMBus communications.

The models accept input voltages from 4.5 to 14V and have an adjustable output voltage range from 0.6 to 5V (1.8V max for 18A model). Designed for a minimal footprint, the LGA modules measure just 12.2 x 12.2 x 8.0mm. The converters offer a typical efficiency figure of 91.6% at 12Vin, and are able to operate in a temperature range of -30 to 95°C.

The operating temperature range is suitable for networking, computing, servers, telecomms, industrial, and other distributed power applications. They are designed to power low-voltage silicon devices such as CPUs, FPGAs, microcontrollers, logic circuits, memory, and other analogue/digital devices in mixed voltage systems.

All power management functions can be reconfigured for user-specific needs using the PMBus interface. 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, says the company. Default firmware configuration is suitable for a range of input voltage, output voltage, and load.
