LN2441 Datasheet (natlinear) - PWM/PFM Automatic Switching Controlled Synchronous DC-DC Converters

LN2441, PWM/PFM Automatic Switching Controlled Synchronous DC-DC Converters

The LN2441 is a constant frequency, current mode step-down converter.

It is ideal for powering portable equipment that runs from a single cell lithium-Ion (Li+) battery.

Switching frequency is internally set at 1.5MHz, allowing the use of small surface mount inductor and capacitors.
