CIRCUITRY AND LDO CONTROLLER  
PRELIMINARY DATA SHEET  
FEATURES  
DESCRIPTION  
Dual Synchronous Controller in 16-Pin Package  
with 1808 out-of-phase operation  
LDO Controller with 40mA drive  
The IRU3048 IC combines a Dual synchronous Buck  
controller and a linear regulator controller, providing a  
cost-effective, high performance and flexible solution for  
multi-output applications. The Dual synchronous con-  
troller is configured as 2-independent PWM controller.  
IRU3048 provides a separate adjustable output by driv-  
ing a switch as a linear regulator. This device features an  
internal 200KHz oscillator, under-voltage lockout for all  
input supplies, an external programmable soft start func-  
tion as well as output under-voltage detection that latches  
off the device when an output short is detected.  
Configured as 2-Independent PWM Controller  
Flexible, Same or Separate Supply Operation  
Operation from 4V to 25V Input  
Internal 200KHz Oscillator  
Soft-Start controls all outputs  
Fixed Frequency Voltage Mode
