Texas Instruments LM5185EVM-SIO Evaluation Module

Texas Instruments LM5185EVM-SIO Evaluation Module facilitates an extensive evaluation of the features and performance of the LM5185-Q1 controller. The LM5185-Q1, Primary-Side Regulated (PSR) flyback controller has adjustable loop compensation and current limit. The TI LM5185EVM-SIO Evaluation Module samples the voltage of the transformer’s primary winding to achieve tight output regulation without an optocoupler or tertiary bias winding. The device offers an input voltage range of 20V to 60V and an output of 16.4V with a rated load of 1A.

Features

Wide input voltage range (default 20V to 60V, extendable 6V to 90V)
Tight voltage regulation of the isolated output without optocoupler at 16.4V ±1.5%
Peak conversion efficiency >90%

Removal of the optocoupler and transformer aux winding saves solution size and cost
Programmable loop compensation, current limit, input UVLO, and thermal compensation allow for flexible and optimal designs

Applications

Traction inverters
Onboard charger (OBC)
HEV/EV HVAC and heater
Micro inverters
Motor drives
Battery Management Systems (BMS)

Generic IGBT, MOSFET, GaN, and SiC gate drivers
PoE PD DC-DC converters
Generic isolated bias power rails for industrial and telecom systems
