HIGH PERFORMANCE CURRENT MODE POWER SWITCH
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) |
