Isolated DC/DC power supply for PLC analog input and output module reference design

The TIDA-00401 TI Design is an isolated DC/DC turn-key solution. For a 10W isolated power supply with wide input voltage range, no opto-coupler feedback and low number of external components the Fly-Buck™ topology is superior to a flyback design. The single side populated PCB board provides a convenient tool for evaluation and on-the-fly optimization of the design, with adequate headers, jumpers and test points for applications like PLC analog Input/Output modules.

Features:
-Isolated DC/DC Power Supply for 15V to 36V Input, up to 10W of Output Power
-Low quiescent current up to 20mA
-Open-Loop, Optocoupler-less Design
-Synchronization Output and Fixed Switching Frequency Enable Use in Noise Sensitive Applications
-Flexible Configurable Board Enables Easy Evaluation and Modification
-Design Guide Provides Detailed Description and Performance Test Data

Parts Include:
LM5160 Wide Input 65V, 1.5A Synchronous Step-Down DC-DC Conv
TPS709 150-mA, 30-V, Ultra-Low IQ, Wide Input Low-Dropout Regulator with Reverse Current Protection
TPS7A30 Vin -3V to -36V, -200mA, Ultra-Low Noise, High PSRR, Low-Dropout Linear Regulator
