The MAX1556ETB+T is a high-efficiency, low-quiescent current step-down regulator designed for portable devices. It operates from a 2.6V to 5.5V input and can deliver up to 1.2A of output current. The device features a 1MHz PWM switching frequency, which allows for the use of small external components like a 3.3µH inductor.
This regulator offers selectable output voltages including 1.8V, 2.5V, and 3.3V, and is also adjustable from 0.75V to 5.5V. It boasts up to 97% efficiency and maintains 95% efficiency at a 1mA load current. Key features include low quiescent current (16µA) and a low shutdown current (0.1µA), making it ideal for battery-powered applications.
The MAX1556ETB+T is housed in a compact 10-pin TDFN (3mm x 3mm) package, suitable for space-constrained designs. It includes an analog soft-start feature to minimize battery transient loading and does not require an external Schottky diode.
Applications for this regulator include PDAs, cell phones, digital cameras, portable MP3 and DVD players, and hand-held instruments. Its design prioritizes efficiency, low power consumption, and minimal component count.
