The Eval Board for the L7987L step-down switching regulator is designed for applications requiring efficient voltage regulation. It supports an input voltage range of 4.5 V to 60 V and can deliver a maximum output current of 2 A with a fixed output voltage of 5 V when the input voltage exceeds 6 V. The device operates at a switching frequency of 500 kHz and features a 5 ms soft-start time to minimize inrush current. This evaluation board is compliant with ceramic output capacitors and includes auto-recovery overcurrent and thermal protection, enhancing reliability in various operating conditions. The L7987L regulator also allows for synchronization in a 180¬8 out-of-phase configuration, which can help reduce total input RMS current. The board is RoHS compliant, making it suitable for environmentally conscious designs.
