UPS703
LINEAR INTEGRATED CIRCUIT
HIGH PERFORMANCE
CURRENT MODE POWER
SWITCH
 DESCRIPTION
The UTC UPS703 is designed for several special
enhancements to satisfy the demands, 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 relative situations.
