PAM2305D
1A STEP-DOWN DC-DC CONVERTER
Description
The PAM2305D is a step-down current-mode, DC-DC converter. At
heavy load, the constant frequency PWM control per forms excellent
stability and transient response. To ensure the longest battery life in
portable applications, the PAM2305D provides a power-saving Pulse-
Skipping Modulation (PSM) mode to reduce quiescent current under
light load operation to save power.
The PAM2305D 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 output voltage is
adjustable from 0.6V to the input voltage. 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.
The PAM2305D is available in TSOT25, DFN2x2-6 Pin and QFN3x3-
16 Pin packages.
