PAM2306
DUAL HIGH-EFFICIENCY PWM STEP-DOWN DC-DC CONVERTER
Description
Pin Assignments
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.
