UNISONIC TECHNOLOGIES CO., LTD
UPS702
LINEAR INTEGRATED CIRCUIT
HIGH PERFORMANCE
CURRENT MODE POWER
SWITCH
„ DESCRIPTION
The UTC UPS702 is designed to provide several special
enhancements to satisfy the needs, for example, Power-Saving
mode for low standby power (<0.3W), Frequency Hopping ,
Constant Output Power Limiting , Slope Compensation ,Over
Current Protection (OCP), Over Voltage Protection (OVP), Over
Load Protection (OLP), Under Voltage Lock Out (UVLO), Short
Circuit Protection (SCP) , Over Temperature Protection (OTP) etc.
IC will be shutdown or can auto-restart in situations.
„ FEATURE
* Low startup current (about 22μA)

* Soft start
* Internal Slope Compensation
* Constant Power Limiting for universal AC input Range
* Gate Output Maximum Voltage Clamp(15V)
* Max duty cycle 74%
* Over temperature protection
* Overload protection
* Over voltage protection
* Leading edge blanking
* Cycle-by-Cycle current limiting
* Under Voltage Lock Out
* Short Circuit Protection
