The PMP15013 reference design is a 5 V/3 A output power supply using the LMR16030 DC/DC buck regulator. This design uses a 4-layer board and is intended for industrial applications with a 24 V input bus. LMR16030 is a 4.5 V to 60 V input, 3 A output capable, and 200 kHz to 2.5 MHz non-synchronous buck regulator. This reference design has an input voltage range of 18 V to 36 V, covering the widely-varying input voltage condition commonly seen in industrial applications with a loosely-regulated nominal 24 V input voltage. The reference board includes an input EMI filter, and the layout is optimized for improved EMI performance on a 4-layer PCB. The board was tested to the CISPR-22 standard, and the conducted emissions (CE) and radiated emissions (RE) were in compliance with the CISPR-22 Class-B requirement with 10 dB of margin.
