Multi Chip Module Family Extended

17:00 14/12/2009

600mA Synch Buck DC/DC + VDR

The XCM524 series is the latest multi chip module (MCM) to be released by Torex and features a 600mA synchronous step-down DC/DC plus a VDR (LDO regulator with on-board voltage detector) enabling high efficiency, low noise and low output voltages to be supplied with minimal external component count !

The DC/DC block has an operating voltage range of 2.7V~6.0V and switching frequency can be selected from 1.2MHz & 3MHz. Control can be either PWM or PWM/PFM automatic switching.
Ouput voltage can be selected within a range of 0.8V~4.0V for the DC/DC output and 0.9V~5.1V for the LDO output.  The voltage detector range is from 2.0V~5.5V. 

Available now in a tiny USP-12B01 package (2.8 x 2.3 x 0.6mm) !
 

XC6223 CMOS High Speed LDO

10:10 23/11/2009

300mA High Speed LDO in 1mm x 1mm x 0.4mm Pkg !

The new XC6223 series from Torex offers not only fast transient response performance coupled with low drop-out voltage, it also features inrush current protection as well as thermal shutdown protection.

Output voltages can be selected in 50mV steps within a range of 1.2V~4.0V and the operating voltage range of the IC is between 1.6V~5.5V.

Available in SOT-89-5, SOT-25 & SSOT-24, the XC6223 will also soon be available in a tiny 1mm x 1mm x 0.4mm USPQ-4 package.
