EVBL4473-L-00A

EVBL4473-L-00A evaluation board is designed to demonstrate the capabilities of the MP/MPQ4473, a high-efficiency, step-down regulator that features an MPS power inductor and integrated power MOSFETs. The MP/MPQ4473 offers a very compact solution to achieve 3.5A of continuous output current (IOUT) with excellent load and line regulation across a wide input supply range. It also provides fast transient response and good stability across a wide input supply and load range. The EVBL4473-L-00A is a Fully assembled and tested evaluation board. It generates a 3.3V output voltage (VOUT) at load currents up to 3.5A across a 4.5V to 36V input voltage (VIN) range. The switching frequency (fSW) is set to 500KHz. The MP/MPQ4473 is available in a QFN-20 (3mmx4mm) package. Typical applications include Notebook Systems and I/O Power, Automotive Systems, Networking Systems, Industrial Supplies, Optical Communications Systems and Distributed Power and Point-of-Load (POL) Systems.
