PAM2301
800mA STEP-DOWN DC-DC CONVERTER
Description
The PAM2301 is a 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 PAM2301 provides a power-saving Pulse-
Skipping Modulation (PSM) mode to reduce quiescent current under
light load operation to save power.
The PAM2301 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, while the part number suffix
PAM2301-XX indicates pre-set output voltage of 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 0.1mA. Other
key features include under-voltage lockout to prevent deep battery
discharge.
The PAM2301 is available in TSOT25 package.
