XC9140 Series

ETR04015-003

Step-UpSynchronous PFM DC/DC Converter

☆GreenOperation Compatible

■GENERAL DESCRIPTION

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

(TYP.) Nch driver transistor and an internal 0.65Ω (TYP.) 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 (XC9140Axx1 type and XC9140Cxx1 type), 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.

The XC9140 features a load disconnect function to break continuity between the input and output at shutdown (XC9140A), and

also a bypass mode function to maintain continuity between the input and output (XC9140C).

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 2.15V (±3.0%), and a

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