SNVS215D April 2003 – November 2015 LM5030
PRODUCTION DATA.
The LM5030 can be used as a controller for push-pull, full bridge or half bridge power supplies. Typical applications are for input voltages up to 100 V and output power around 30 W with switching frequency up to
1 MHz.
Care should be taken that components with the correct current rating are chosen. This includes magnetic components, power MOSFETs and diodes, connectors and wire sizes. Input and output capacitors should have the correct ripple current rating.
The VCC pin requires a local decoupling capacitor that is connected to GND. This capacitor ensures stability of the internal regulator from the VIN pin. The decoupling capacitor also provides the current pulses to drive the gates of the external MOSFETs through the driver output pins.
Place the decoupling capacitor close to the VCC and GND pins and track it directly to these pins.
