Integrated inductor: low noise, low EMI
EP5358xUI adopts a proprietary low loss integrated inductor. The integration of inductors greatly simplifies the power supply design process. The inherent shielding and compact structure of integrated inductors reduce the coupling of conducted and radiated noise to the trace board of the printed circuit. In addition, the packaging layout is optimized to reduce the electrical path length for high di/dt input AC ripple current from the main source of radiation in DC-DC converters. The integrated inductor provides the optimal solution for complexity, and the design of low-power DCDC converters troubled by output ripple and noise.diode
Overcurrent/short circuit protection
The current limiting function is achieved by sensing the current flowing through the P-MOSFET and its reference current. When this level exceeds the cutoff of the P-field-effect transistor and the conduction of the N-type field-effect transistor, the pull VOUT is low. Maintain this condition for approximately 0.5 milliseconds, and then start a normal soft start. If the overcurrent situation still exists, this cycle will be repeated.
thermal shutdowndiode
When too much power is dissipated in the chip, the junction temperature rises. Once the junction temperature exceeds the thermal shutdown temperature, the thermal shutdown circuit shuts off the output voltage of the converter, thereby cooling the device. When the junction temperature reaches 15C ° C, the equipment will go through the normal startup process.
