DESCRIPTION

The UTC UCS1602S is an integrated PWM controller and

Power MOSFET specifically designed for switching operation with

minimal external components. The UTC UCS1602S is designed

to provide several special enhancements to satisfy the needs, for

example, Power-Saving mode for low standby power, Frequency

Hopping,

Constant

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.
