Dual, 4A/2A, 4MHz, Step-Down DC-DC Regulator With Tracking/Sequencing Capability

The MAX15021 is a dual-output, pulse-width-modulated (PWM), Step-down DC-DC Regulator with tracking (coin- cident and ratiometric) and sequencing options. The device operates from 2.5V to 5.5V and each output CAN be adjusted from 0.6V to the input supply (VAVIN). The MAX15021 delivers up to 4A (regulator 1) and 2A (reg- ulator 2) of output current. This device offers the ability to adjust the switching frequency from 500kHz to 4MHz and provides the capability of optimizing the design in terms of size and performance. The MAX15021 is available in a space-saving, 5mm x 5mm, 28-pin TQFN-EP package and is specified for operation from -40C to +125C temperature range. By Maxim Integrated Products
