DESCRIPTION

The UTC UCS17005S is an integrated PWM controller and

Power MOSFET specifically designed for switching operation

with minimal external components. The UTC UCS17005S 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-restart in situations.



FEATURE

* Internal Power MOSFET (700V)

* Lower than 30mW Standby Power Design

* Linearly decreasing frequency to 20~35KHz during light load

* Internal Soft start

* Internal Slope Compensation

* Constant Power Limiting for universal AC input Range

* Gate Output Maximum Voltage Clamp(16V)

* Over temperature protection

* Over load protection

* Over voltage protection

* Leading edge blanking

* Cycle-by-Cycle current limiting

* Under Voltage Lock Out
