The MAX1974EUB+T is a constant-frequency, 1.4MHz pulse-width-modulated (PWM) current-mode step-down regulator. It supports an input voltage range of 2.6V to 5.5V and can deliver up to 1A of output current. The output voltage is adjustable from 0.75V to VIN, providing flexibility for various applications.
This regulator operates at a fixed 1.4MHz switching frequency, ensuring operation outside the DSL frequency band and enabling fast transient response with small external components. It requires only 4.7µF ceramic input and output capacitors for 1A applications. The device features forced PWM operation for a constant switching frequency across all load conditions and offers 100% duty-cycle dropout capability.
The MAX1974EUB+T is available in a compact 10-pin µMAX package, suitable for applications where space is limited. Its tiny circuit footprint of 0.19in² and ultra-low circuit height of 1.8mm make it ideal for designs with strict dimensional constraints. The operating temperature range is -40°C to +85°C.
Applications include network equipment, cellular base stations, DSL and wireless modems/routers, optical modules, and DSP/ASIC core and IO supplies.
