PAM2308数据手册集成电路（IC）的稳压器-DC-DC开关稳压器规格书PDF

描述 Description

The PAM2308 is a dual step-down current-mode, DC-DC converter.
At heavy load, the constant frequency PWM control performs
excellent stability and transient response. To ensure the longest
battery life in portable applications, the PAM2308 provides a powersaving
Pulse- Skipping Modulation (PSM) mode to reduce quiescent
current under light load operation.

The PAM2308 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 0.1μA. Other key features
include under-voltage lockout to prevent deep battery discharge.
