Flex Power Modules PNA 6A output non-isolated DC-DC PoL converters

Flex Power Modules announces PNA series 6A output non-isolated DC-DC PoL converters

The PNA series is an analogue non-isolated point of load (PoL) regulator that offers excellent efficiency and thermal performance in a small form factor. Its compact size and wide input voltage range of 9V to 36V mean that it is ideal for a range of industrial applications, including robotics, factory automation and process control, and that it is suitable for both 12V and 24V power systems.

The regulator has high efficiency of 95.5% at 12Vin and 5.5Vout, at full load. This reduces power losses and heat dissipation. It delivers an adjustable output of 0.9V to 5.5V, at up to 6A output current, which translates to a maximum power output of 33W.

The PNA series provides excellent thermal performance, and can operate at full load in ambient temperatures above +100°C. It has an operating temperature range of -40°C to +125°C.

To save board space, the PNA series is provided in a small form factor, measuring 13mm x 12.35mm x 6.2 mm (0.512'' x 0.486'' x 0.244''). The device also supports bottom-side PCB mounting, thus further reducing board space requirements.

The regulator is available at a competitive cost, and provides an attractive price/performance ratio. It offers a Mean Time Between Failures (MTBF) of up to 71.84 million hours.

A voltage tracking function enables one regulator to use the output voltage of another as a reference to follow its turn-on and turn-off behavior. This simplifies the design required to make each device power-up in the correct sequence. The regulator also includes a power good (PG) function, for further control of sequencing, and supports soft start with time-based sequencing.

The PNA series can be synchronized to an external clock, which means that it eliminates beat frequencies reflected back to the input supply rail.
