A Product Line of Diodes Incorporated PAM2309 1A STEP-DOWN DC-DC CONVERTER Description The PAM2309 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 PAM2309 provides a power-saving PulseSkipping Modulation (PSM) mode to reduce quiescent current under light load operation to save power. The PAM2309 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.
