All 15 point-of-load (POL) converters in Artesyn’s PTH series are available in through-hole and surface-mount versions. The converters all offer wide output voltage adjustability, set via a single resistor, together with an on/off inhibit function and output overcurrent protection with automatic recovery. They also feature the Auto-track™ power sequencing function that enables multiple converters to track each other, or an external voltage, during power-up and power-down. This built-in sequencing capability significantly simplifies on-board power provision for today’s PCBs, where devices such as DSPs, FPGAs and ASICs often demand carefully controlled turn-on and turn-off of their various supply voltages.
Artesyn’s PTH series POL converters offer OEMs a wealth of choice to help simplify design-in. They are available with nine different current outputs from 6 A to 30 A, and with nominal input voltages of 3.3 V, 5 V or 12 V, to suit the designer’s choice of intermediate bus voltage. The converters’ widely adjustable output voltages enable them to satisfy virtually all the supply requirements of low voltage silicon. The 3.3-V input models can have their outputs set to any voltage from 0.8 Vdc to 2.5 Vdc; the 5-V input models have an output range of 0.8 Vdc to 3.6 Vdc; and the 12-V input models have an output range of 1.2 Vdc to 5.5 Vdc.
The 12-V input models are ideal for use with low-cost intermediate bus converters, instead of isolated bricks, for applications where cost is critical. Furthermore, the POL converters’ sequencing capabilities mean that designers can now implement complex distributed power schemes without having to use multiple isolated bricks or purpose-designed circuitry to provide the sequencing functions, thereby achieving significant savings in development time and cost.
