UD18204 Datasheet

18V/2A HIGH EFFICIENCY SYNCHRONOUS RECTIFIED 
STEP-DOWN DC/DC CONVERTER
 
 
 
DESCRIPTION
 
The UTC UD18204 is a high efficiency synchronous step-down
DC/DC converter output up current to 2A continuous output current
supplied.
UTC UD18204 built-in over-current protection, thermal
protection and Under Voltage Lockout (UVLO) circuit is provided to
prevent start-up until the input voltage to 4.5V.
UTC UD18204 is designed as the power saving mode to reduce
the switching frequency to improve the light load efficiency.
   
FEATURES
 
* Input Voltage Supply Range from 4.5V to 18V
* High Efficiency up to 90%
* Adjustable Output Voltage from 0.6V to 12V
* Power Saving Mode (PSM) during the light Load Operation
* Typical 500kHz Frequency Operation
* Current Mode Operation
* Over-temperature Protection
* Over-current Protection
