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.
