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

General Description

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.

LN2441 PWM/PFM Automatic Switching Controlled Synchronous DC-DC Converters ■ General Description 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. Automatic PWM/PFM mode operation increases efficiency and decreases output voltage ripple at light loads, further extending battery life. ■ Features  High Efficiency: 96％  1.
