XC9140 Series

ETR04015-008

Step-UpSynchronous PFM DC/DC Converter

☆Green Operation Compatible

■ GENERAL DESCRIPTION

The XC9140 series are step-up synchronous DC/DC converters that support ceramic capacitors and have an internal 0.6Ω

Nch driver transistor and an internal 0.65Ω Pch synchronous rectifier switch transistor. PFM control enables a low quiescent

current, making these products ideal for portable devices that require high efficiency.

When the output voltage is 3.3V and the load current is 1mA, startup from an input voltage of V_IN= 0.9V is possible which means

that these products can be used in applications that start using a single alkaline or nickel-metal hydride battery. The output voltage can

be set from 1.8V to 5.0V (±2.0%) in steps of 0.1V.

A version with a UVLO (Under Voltage Lock-out) function is also available. This function enables the prevention of battery leakage by

stopping IC’s operation when the input voltage is low. The standard product has a UVLO release voltage of 1.65V, 2.15V and a

custom version with a release voltage selectable from between 1.65V to 2.2V, in steps of 0.05V, is also available.
