DUAL HIGH-EFFICIENCY PWM STEP-DOWN DC-DC CONVERTER

Description

The PAM2306D 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 cur rent 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.
