PNA series

9-36 V input, 6 A output Non-Isolated DC/DC PoL Converter

The PNA series is an analog 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 9 V to 36 V 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 12 V and 24 V power systems.

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

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 13 x 12.35 x 6.2 mm (0.512 x 0.486 x 0.244 in). 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.

The first device in the series, the PNA2405S3S, is available now. Samples are also available now.
