MAXIM INTEGRATED / ANALOG DEVICES MAX1972EEE Dual Buck Regulator

The MAX1972EEE+ from Maxim Integrated Products is a dual, out-of-phase, 1.4 MHz, 750 mA step-down (buck) regulator with power-on reset and power fail functions in a 16-pin QSOP package. It features two current mode PWM buck regulators operating from 2.6V to 5.5V input, delivering at least 750mA each. The high switching frequency allows for smaller inductors and capacitors, with regulators operating 180° out of phase to reduce input ripple. Output voltages are programmable from 1.2V to Vin via external resistors or preset to standard voltages such as 1.8V, 3.3V, 1.5V, and 2.5V. It offers better than ±1% accuracy across load, line, and temperature, with internal soft-start to minimize inrush current. Additional features include a 175ms power-on reset delay, power fail detection, and operation outside the xDSL frequency band. Supports all ceramic capacitors, suitable for gigabit SFP, GBIC modules, dual LDO replacements, USB-powered devices, xDSL modems, and routers, with a temperature range of -40°C to +85°C.
