GENERAL DESCRIPTION
SF6010R is a high precision, highly integrated DCM
(Discontinuous Conduction Mode) Primary Side
Regulation (PSR) controller for offline small power
converter applications. It can directly drive power BJT,
which can further lower system cost. The IC
integrates proprietary “Audio Noise Cancellation”
control for audio noise free operation.
SF6010R has built-in proprietary NC-Cap/PSRTM
control for CV control, which eliminates external
compensation or filtering capacitor. It has built-in
cable drop compensation function, which can provide
excellent CV performance. The IC uses Multi Mode
Control to improve efficiency and reliability and to
decrease audio noise energy @ light loadings. The
IC can achieve less than 70mW standby power.
SF6010R integrates proprietary “Zero-Output
Startup” control to achieve startup when output is
near zero voltage. The IC also has proprietary
“Smart Output Short Protection”, which can limit
maximum power when output is short circuit.
SF6010R integrates functions and protections of FB
Short Protection, Under Voltage Lockout (UVLO),
VDD Over Voltage Protection (VDD OVP), Soft Start,
Cycle-by-cycle Current Limiting (OCP), Pin Floating
Protection, VDD Clamping.
SF6010R is available in SOT23-5 and SOT23-6
packages.
