9 Power Supply Recommendations

The LM5035 can be used to control power levels up to 500 W; therefore, the current levels can be considerable. Care must be taken in choosing components with the correct current rating which includes: magnetic components, power MOSFETS and diodes, connectors, and wire sizes. Input and output capacitors must have the correct ripple current rating. The use of a multilayer PCB is recommended with a copper area chosen to ensure the LM5035 operates below the maximum junction temperature.

Full power loading must never be attempted without providing for adequate cooling.
