Small form factor PoL regulator offers high efficiency and excellent thermal performance

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 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 PNA 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.

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, will be available in Q2/2021. Samples are available now. Customers can obtain further information by contacting pm.info@flex.com
