

DESCRIPTION

The UTC UCS1657S is an integrated PWM controller and

Power MOSFET specifically designed for switching operation with

minimal external components. The UTC UCS1657S 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.



FEATURES

* Internal Power MOSFET (650V)

* Programming Gate Driver Capability

* Frequency hopping for Improved EMI Performance.

* 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

* Overload protection

* Over voltage protection

* Leading edge blanking

* Cycle-by-Cycle current limiting

* Under Voltage Lock Out
