DESCRIPTION

The UTC UPS701 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
