ES2442ES2442

General Description

The ES2442 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％

 1.5MHz Constant Switching Frenquency

 Output Current: 1A

 Shutdown Current: <1uA

 Short Circuit Protection
