UCS1655S Datasheet

HIGH PERFORMANCE CURRENT MODE POWER SWITCH
 
 
 
 
DESCRIPTION
 
The UTC UCS1655S is an integrated PWM controller and Power
MOSFET specifically designed for switching operation with minimal
external components. The UTC UCS1655S is designed to provide
several special enhancements to satisfy the needs, for example,
Power-Saving mode for low standby power, 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), Over Temperature
Protection (OTP), etc. IC will be shutdown or can auto-restartin
situations.


FEATURES
 
* Internal PowerMOSFET (650V) 
* Gate Output Maximum Voltage Clamp(16V)
* Programming Gate Driver Capability 
* Over temperature protection
* Frequency hopping for Improved EMI Performance. 
* Overload protection
* Lower than 0.3W Standby Power Design 
* Over voltage protection
* Linearly decreasing frequency to 26KHz during light load 
* Leading edge blanking
* Internal Soft start 
* Cycle-by-Cycle current limiting
* Internal Slope Compensation 
* Under Voltage Lock Out
* Constant Power Limiting for universal AC input Range
