What are the key features of PLMR36520ADDAR?
- Wide 4.2 V to 65 V input range covers 12 V, 24 V, and 48 V industrial rails with a single design
- 2 A synchronous step-down topology with current-mode control delivers high efficiency across 1 V to 61.75 V adjustable output range
- Pulse Frequency Modulation at light loads minimises quiescent current, extending battery and solar-harvesting runtimes
- 8-pin SO PowerPAD package with integrated thermal pad enables compact, high-dissipation layouts for harsh -40 °C to 125 °C environments
What is PLMR36520ADDAR used for?
PLMR36520ADDAR targets industrial automation, factory sensors, and building-control nodes powered from 24 V or 48 V bus rails where a compact regulated supply is needed from a single IC. Its 65 V input tolerance suits motor-drive auxiliary supplies and telecom equipment that experience high-voltage transients. The wide temperature range and SO-8 PowerPAD footprint also make it attractive for automotive body-electronics and outdoor instrumentation designs.

Frequently Asked Questions
How wide is the input voltage range of PLMR36520ADDAR and which industrial bus rails does it directly support?
PLMR36520ADDAR accepts 4.2 V to 65 V at its input, covering 5 V, 12 V, 24 V, and 48 V industrial bus standards without additional pre-regulation. The 65 V absolute maximum also accommodates load-dump transients on 24 V automotive and telecom rails, letting designers use a single converter across multiple product variants without redesign.
What output voltage range can PLMR36520ADDAR regulate to, and how is it set?
The output voltage is adjustable from 1 V to 61.754 V using a resistor divider on the feedback pin. With a 2 A rated output current, this covers a 2 W to over 120 W output power range, enabling the same IC to power 3.3 V logic, 5 V interfaces, or higher-voltage analog rails within one design.
For a 24 V industrial sensor node, how does PLMR36520ADDAR's PFM mode help with power budget?
At light loads typical of sensor idle states, PLMR36520ADDAR automatically transitions to Pulse Frequency Modulation, reducing switching losses and quiescent current compared to fixed-frequency operation. This keeps standby conversion efficiency high even when the 2 A rated load drops to tens of milliamps, directly extending battery life or reducing thermal rise in sealed enclosures operating from −40 °C to 125 °C.
What are the key thermal advantages of the SO-8 PowerPAD package used by PLMR36520ADDAR?
The R-PDSO-G8 (SO-8 PowerPAD) package incorporates an exposed thermal pad on the underside that bonds directly to the PCB copper pour, significantly lowering junction-to-board thermal resistance compared to standard SO-8 packages. This allows PLMR36520ADDAR to sustain its full 2 A output at the 125 °C maximum ambient rating with proper copper-area design, without requiring an external heatsink.
