1. Description

The PAM2306DYPAA 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 PAM2306D provides a powersaving Pulse-Skipping Modulation (PSM) mode to reduce quiescent current under light load operation. The PAM2306D 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 adjustment. 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.
