MAX748AEWE+ [Analog Devices]

The MAX748A/MAX763A are 3.3V-output CMOS step-down switching regulators designed for high-efficiency power conversion. They accept input voltages from 3.3V to 16V (MAX748A) or 3.3V to 11V (MAX763A) and deliver up to 500mA output current with efficiencies of 85% to 90%. Featuring current-mode PWM control, they provide precise output regulation (±5% accuracy) and excellent transient response. The devices include cycle-by-cycle current limiting, overcurrent protection, undervoltage lockout, and programmable soft-start. A 22µH inductor is preselected for most applications, eliminating the need for magnetic design. They are available in 8-pin DIP and SO packages.
