MAX1951A Datasheet | Maxim Integrated

19-4689; Rev 0; 7/09 KIT ATION EVALU E L B A IL AVA .. 1MHz, 2A, 2.6V to 5.5V Input, PWM DC-DC Step-Down Regulator with Enable General Description The MAX1951A high-efficiency, DC-DC step-down switching regulator delivers up to 2A of output current. The device operates from an input voltage range of 2.6V to 5.5V and provides an adjustable output voltage from 0.8V to VIN, making the MAX1951A ideal for on-board postregulation applications. The MAX1951A total output error is less than ±1.5% over load, line, and temperature. The MAX1951A operates at a fixed frequency of 1MHz with an efficiency of up to 94%. The high operating frequency minimizes the size of external...
