PNA series

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 V_in and 5.5 V_out, 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 (hot spot temperature) .

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.
