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.
