DESCRIPTION  
The LM26484 is a multi-function, configurable Power  
Management Unit. This device integrates two highly  
efficient 2.0A Step-Down DC/DC converters, one  
LDO Controller, a POR (Power On Reset) circuit, and  
thermal overload protection circuitry. All regulator  
output voltages are externally adjustable. The LDO  
controller is a low-voltage NMOS voltage regulator.  
The LM26484 is offered in a 5 x 4 x 0.8 mm WQFN-  
24 pin package.
