PoL regulator offers high efficiency and improved thermal performance
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.
The first device in the series, the PNA2405S3S, will be available in Q2/2021.
