UC3848

LINEAR INTEGRATED CIRCUIT

HIGH PERFORMANCE CURRENT

MODE CONTROLLERS

DESCRIPTION

The UTC UC3848 is designed to provide several special

enhancements to satisfy the needs, for example, Power-Saving mode

for low standby power (<0.3W), 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), Short Circuit Protection (SCP) , Over

Temperature Protection (OTP) etc. IC will be shutdown or can

auto-restart in situations.

FEATURES

* Low Startup Current (about 22μA)

* Fixed Switching Frequency(Norm. is 68KHz)

* Frequency Hopping for Improved EMI Performance.

* Lower than 0.3W Standby Power Design

* Linearly Decreasing Frequency to 26KHz During Light Load

* Soft Start

* Internal Slope Compensation

* Constant Power Limiting for Universal AC input Range

* Gate Output Maximum Voltage Clamp(15V)

* Max Duty Cycle 74%

* Over Temperature Protection

* Overload Protection

* Over Voltage Protection

* Leading Edge Blanking

* Cycle-by-Cycle Current Limiting

* Under Voltage Lock Out

* Short Circuit Protection
