Overview

Product D2312 Product Info 1A Step-Down DC-DC Converter Description The D2312 is a step-down current-mode, DC-DC converter.
A theavy load, the constant-frequency PWM control performs excellent stability and transient response.
To ensure the longest battery life in portable applications, the D2312 provides a power-saving Pulse-Skipping Modulation (PSM) mode to reduce quiescent current under light load operation to save power.
The D2312 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 D2312- 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 rectifierfor to minimize external part count and realize high efficiency.
During shutdown, the input is disconnected from the output and th...
