Flex Power Modules has announced the PNA series of analogue non-isolated point of load (PoL) regulators that offer improved levels of efficiency and thermal performance in a small form factor.

These regulators come in a compact size and offer a wide input voltage range of 9 V to 36 V meaning that they are suitable for a range of industrial applications, including robotics, factory automation and process control.

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 offers good 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 series is provided in a small form factor, measuring 13 x 12.35 x 6.2 mm (0.51 x 0.48 x 0.24 in). This supports bottom-side pcb mounting, thus further reducing space requirements.

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.
