ROHM Semiconductor BD9G341AEFJ-EVK Evaluation Board

Das Evaluation-Board ROHM BD9G341AEFJ-EVK wurde zur Auswertung der Synchron-Abwärtswandler BD9G341AEFJ entwickelt. Es arbeitet mit einer Stromversorgung von 12 bis 76 Volt und produziert eine Ausgabe von 5 Volt. Der Schaltkreis hat einen internen 150mΩ N-channel MOSFET. Betriebsfrequenzen können zwischen 50 kHz und 750 kHz programmiert werden.

A fixed Soft Start circuit prevents inrush current during startup along with UVLO (low voltage error prevention circuit) and TSD (thermal shutdown detection), OCP (over current protection), OVP (over voltage protection) protection circuits. An EN pin allows for simple ON/OFF control of the IC to reduce standby current consumption.
