Description

The PAM2306 is a dual step-down current-mode, DC-DC converter. At heavy load, the constant frequency PWM control provides excellent stability and transient response. To ensure the longest battery life in portable applications, the PAM2306 provides a power - saving Pulse-Skipping Modulation (PSM) mode to reduce quiescent current under light load operation. The PAM2306 supports a range of input voltages from 2.5V to 5.5V, allowing the use of a single Li+/Li-polymer cell, multiple Alkaline/NiMH cell, USB, and other standard power sources. The dual output voltages are available for 3.3V, 2.8V, 2.5V, 1.8V, 1.5V, 1.2V or adjustable. All versions employ internal power switch and synchronous rectifier to minimize external part count and realize high efficiency. During shutdown, the input is disconnected from the output and the shutdown current is less than 0.1A. Other key features include under-voltage lockout to prevent deep battery discharge.
