The MAX748AEWE+ from Analog Devices (formerly Maxim Integrated) is a 3.3V output, step-down (buck) switching regulator designed for efficient power conversion. It accepts input voltages from 3.3V to 16V and can deliver a continuous output current of up to 500mA.
This device utilizes pulse-width modulation (PWM) current-mode control for precise output regulation and excellent transient response. It guarantees an output voltage accuracy of ±5% over variations in line, load, and temperature. The fixed-frequency switching operation, typically between 159kHz and 219.5kHz, simplifies output filtering and allows for the use of small external components, including a preselected 22µH inductor.
Key features include cycle-by-cycle current limiting, overcurrent limiting, undervoltage lockout, and programmable soft-start protection. The MAX748AEWE+ is housed in a 16-SOIC package, suitable for surface mounting. Its typical operating temperature range is -40°C to 85°C.
Applications for this regulator include 5V-to-3.3V converters, cellular phones, portable instruments, hand-held computers, and computer peripherals.
