DESCRIPTION

Your power supply problems just got SUPER SOLVED! This 3.3V Buck Converter

Breakout board is great for supplying power to low voltage circuits from a single

Li-Ion cell battery or USB power.  This chip provides up to 600-mA load current

across the entire input voltage range of 3.5 to 5.5V.  Great for your portable

project, we made this "pin compatible" with the LM1117-3.3V TO-220 chip so you

can swap it in for better performance (90-95% efficiency!) There's also an ENable

pin, tie it low to shut down the output completely.

There's a 2-MHz fixed-frequency in PWM mode and PFM mode extends the battery

life by reducing the current during light load or standby operation.

Comes with a fully assembled and tested breakout board.  We also include header

to plug it into a breadboard.
