Flex Power Modules announces the PNA series, an analog non-isolated point of load (PoL) regulator offering excellent efficiency and thermal performance.

According to a company press release, 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.
  • Process control.
  • Being suitable for both 12 V and 24 V power systems.


The PNA series has an operating temperature range of -40 °C to + 125 °C and is provided in a small form, measuring 13 x 12.35 x 6.2 mm (0.51 x 0.48 x 0.24 in). The design supports bottom-side PCB mounting.


Using a voltage tracking function simplifies the design required to make each device power-up in the correct sequence. The regulator also includes a power good (PG) function and supports soft start with time-based sequencing. Synchronizing the PNA series to an external clock eliminates beat frequencies reflected to the input supply rail.
