The MAX1556ETB+T is a high-efficiency, low-quiescent current step-down DC-DC converter designed for portable devices. It operates from a 2.6V to 5.5V input voltage and can deliver up to 1.2A of output current.
This regulator features a 1MHz PWM switching frequency, which allows for the use of small external components like a 3.3µH inductor. It offers selectable and adjustable output voltages, with a minimum fixed output of 0.75V and a maximum of 5.5V. The device boasts up to 97% efficiency and maintains 95% efficiency at a 1mA load current, with a low quiescent current of 16µA.
The MAX1556ETB+T includes an internal MOSFET switch and synchronous rectifier to maximize efficiency and minimize external component count. It also features an analog soft-start function to minimize battery transient loading. The converter is available in a compact 10-pin TDFN (3mm x 3mm) package, suitable for space-constrained applications.
Applications for this device include PDAs, cell phones, digital cameras, portable MP3 players, and hand-held instruments. Its low dropout, low quiescent current, and high efficiency make it ideal for battery-powered portable equipment.
