Product Description

PWM/PFM Synchronous Step-Up DC/DC Converter

The XC9144 is a 18V 1.0A synchronous step-up DC/DC converter that can operate within a wide range of 1.7V~16V and can support output voltages of between 7.0V~18V (set externally). There are two switching frequency options available, 1.2MHz and 3.0MHz and this new boost DC/DC can support output currents of up to 400mA (VOUT=7.0V, VIN=3.3V) or 400mA (VOUT=12V, VIN=5.0V)

The XC9144 is an ideal solution for use in a variety of applications where there is a requirement to step-up from either a battery or DC inputs such as 5V and 12V to power displays, motors, actuators, or various analogue circuits.

An efficient step-up circuit can be configured using only a minimum of external components and a small 2.2uH inductor (3.0MHz version) which also helps reduce output ripple voltage.

This series also features an inrush current prevention circuit and a thermal shutdown circuit.

The XC9144 is available in the USP-6C package.
