MAX15050/51: 4A, synchronous DC-DC regulators with integrated MOSFETs achieve 96% efficiency in 4mm2 package

Maxim Integrated Products introduces the MAX15050/MAX15051, low-voltage (2.9V to 5.5V), 4A, synchronous DC-DC regulators in a 2mm x 2mm wafer-level package (WLP). These tiny step-down regulators integrate MOSFETs to simplify design, minimize EMI, and save board space. Operation from a fixed 1MHz switching frequency further reduces total solution size, allowing all-ceramic-capacitor designs. Offering peak efficiencies up to 96%, these point-of-load converters minimize power losses in applications ranging from portable devices to networking equipment.
